Find the mean and the standard deviation. a. \(X =\) a real number between \(a\) and \(b\) (in some instances, \(X\) can take on the values \(a\) and \(b\)). The waiting time for a bus has a uniform distribution between 0 and 10 minutes. A form of probability distribution where every possible outcome has an equal likelihood of happening. 23 There is a correspondence between area and probability, so probabilities can be found by identifying the corresponding areas in the graph using this formula for the area of a rectangle: . Suppose it is known that the individual lost more than ten pounds in a month. A fireworks show is designed so that the time between fireworks is between one and five seconds, and follows a uniform distribution. =0.8= 1 = The 30th percentile of repair times is 2.25 hours. Find the probability that the time is more than 40 minutes given (or knowing that) it is at least 30 minutes. ( for 0 x 15. The Uniform Distribution by OpenStaxCollege is licensed under a Creative Commons Attribution 4.0 International License, except where otherwise noted. 1 2 That is, find. = The probability density function of \(X\) is \(f(x) = \frac{1}{b-a}\) for \(a \leq x \leq b\). When working out problems that have a uniform distribution, be careful to note if the data is inclusive or exclusive of endpoints. For the second way, use the conditional formula from Probability Topics with the original distribution X ~ U (0, 23): P(A|B) = P(x>8) What is the probability that the waiting time for this bus is less than 6 minutes on a given day? The data that follow are the number of passengers on 35 different charter fishing boats. In this framework (see Fig. For example, in our previous example we said the weight of dolphins is uniformly distributed between 100 pounds and 150 pounds. X ~ U(0, 15). The unshaded rectangle below with area 1 depicts this. So, mean is (0+12)/2 = 6 minutes b. c. This probability question is a conditional. . The sample mean = 7.9 and the sample standard deviation = 4.33.

The sample mean = 11.49 and the sample standard deviation = 6.23. 230 Notice that the theoretical mean and standard deviation are close to the sample mean and standard deviation in this example. 5 P(X > 19) = (25 19) \(\left(\frac{1}{9}\right)\) 2.5 The lower value of interest is 0 minutes and the upper value of interest is 8 minutes. This means you will have to find the value such that \(\frac{3}{4}\), or 75%, of the cars are at most (less than or equal to) that age. Let \(X =\) the time needed to change the oil on a car. a+b The concept of uniform distribution, as well as the random variables it describes, form the foundation of statistical analysis and probability theory. Find the third quartile of ages of cars in the lot. Write the probability density function. What percentile does this represent? Find the probability that she is between four and six years old. 14.6 - Uniform Distributions. P(x 2) = (base)(height) = (4 2)(0.4) = 0.8, b. P(x < 3) = (base)(height) = (3 1.5)(0.4) = 0.6. In statistics, uniform distribution is a probability distribution where all outcomes are equally likely. 2 = For the second way, use the conditional formula from Probability Topics with the original distribution \(X \sim U(0, 23)\): \(P(\text{A|B}) = \frac{P(\text{A AND B})}{P(\text{B})}\). There are several ways in which discrete uniform distribution can be valuable for businesses. Uniform distribution is the simplest statistical distribution. Uniform distribution: happens when each of the values within an interval are equally likely to occur, so each value has the exact same probability as the others over the entire interval givenA Uniform distribution may also be referred to as a Rectangular distribution The Bus wait times are uniformly distributed between 5 minutes and 23 minutes. Find \(P(x > 12 | x > 8)\) There are two ways to do the problem. The data in [link] are 55 smiling times, in seconds, of an eight-week-old baby. The graph of the rectangle showing the entire distribution would remain the same. 15 The data that follow are the number of passengers on 35 different charter fishing boats. obtained by dividing both sides by 0.4 The uniform distribution defines equal probability over a given range for a continuous distribution. 2 This means you will have to find the value such that \(\frac{3}{4}\), or 75%, of the cars are at most (less than or equal to) that age. Financial Modeling & Valuation Analyst (FMVA), Commercial Banking & Credit Analyst (CBCA), Capital Markets & Securities Analyst (CMSA), Certified Business Intelligence & Data Analyst (BIDA), Financial Planning & Wealth Management (FPWM). 2.5 Continuous Uniform Distribution Example 2 2.75 Statology Study is the ultimate online statistics study guide that helps you study and practice all of the core concepts taught in any elementary statistics course and makes your life so much easier as a student. The waiting times for the train are known to follow a uniform distribution. However, there is an infinite number of points that can exist. A random number generator picks a number from one to nine in a uniform manner. Not sure how to approach this problem. 0+23 a is zero; b is 14; X ~ U (0, 14); = 7 passengers; = 4.04 passengers. . So, P(x > 21|x > 18) = (25 21)\(\left(\frac{1}{7}\right)\) = 4/7. What is the probability that the rider waits 8 minutes or less? 5 Uniform Distribution between 1.5 and 4 with an area of 0.25 shaded to the right representing the longest 25% of repair times. 1 To find f(x): f (x) = \(\frac{1}{4\text{}-\text{}1.5}\) = \(\frac{1}{2.5}\) so f(x) = 0.4, P(x > 2) = (base)(height) = (4 2)(0.4) = 0.8, b. P(x < 3) = (base)(height) = (3 1.5)(0.4) = 0.6. Then X ~ U (6, 15). 11 A continuous probability distribution is called the uniform distribution and it is related to the events that are equally possible to occur. You are asked to find the probability that an eight-week-old baby smiles more than 12 seconds when you already know the baby has smiled for more than eight seconds. 238 Find the upper quartile 25% of all days the stock is above what value? If the waiting time (in minutes) at each stop has a uniform distribution with A = 0 and B = 5, then it can be shown that the total waiting time Y has the pdf f(y) = 1 25 y 0 y < 5 2 5 1 25 y 5 y 10 0 y < 0 or y > 10 Let X = the number of minutes a person must wait for a bus. \(0.90 = (k)\left(\frac{1}{15}\right)\) Correct answers: 3 question: The waiting time for a bus has a uniform distribution between 0 and 8 minutes. Then \(X \sim U(6, 15)\). Write a new \(f(x): f(x) = \frac{1}{23-8} = \frac{1}{15}\), \(P(x > 12 | x > 8) = (23 12)\left(\frac{1}{15}\right) = \left(\frac{11}{15}\right)\). When working out problems that have a uniform distribution, be careful to note if the data is inclusive or exclusive. (In other words: find the minimum time for the longest 25% of repair times.) In statistics, uniform distribution is a term used to describe a form of probability distribution where every possible outcome has an equal likelihood of happening. Use Uniform Distribution from 0 to 5 minutes. The probability that a nine-year old child eats a donut in more than two minutes given that the child has already been eating the donut for more than 1.5 minutes is 4545. Draw a graph. \(0.3 = (k 1.5) (0.4)\); Solve to find \(k\): 15 P(x>8) Find the probability that the time is between 30 and 40 minutes. A subway train on the Red Line arrives every eight minutes during rush hour. Let X = the time, in minutes, it takes a student to finish a quiz. \(0.625 = 4 k\), First way: Since you know the child has already been eating the donut for more than 1.5 minutes, you are no longer starting at a = 0.5 minutes. Ace Heating and Air Conditioning Service finds that the amount of time a repairman needs to fix a furnace is uniformly distributed between 1.5 and four hours. The data follow a uniform distribution where all values between and including zero and 14 are equally likely. 1. = \(\sqrt{\frac{\left(b-a{\right)}^{2}}{12}}=\sqrt{\frac{\left(\mathrm{15}-0{\right)}^{2}}{12}}\) = 4.3. a. \(f(x) = \frac{1}{9}\) where \(x\) is between 0.5 and 9.5, inclusive. The histogram that could be constructed from the sample is an empirical distribution that closely matches the theoretical uniform distribution. 0.25 = (4 k)(0.4); Solve for k: You will wait for at least fifteen minutes before the bus arrives, and then, 2). Solve the problem two different ways (see Example). 15 Find the 90th percentile for an eight-week-old babys smiling time. Find the probability. Uniform Distribution between 1.5 and four with shaded area between two and four representing the probability that the repair time, Uniform Distribution between 1.5 and four with shaded area between 1.5 and three representing the probability that the repair time.
