Consider a uniform distribution from a = 4 to b= 28. (a) Find the probability that x lies between 7 and 22. (b) Find the probability that x lies between 8 and 25. (c) Find the probability that x lies between 11 and 17. (d) Find the probability that x lies between 5 and 13. Click the icon to see the definition of the uniform distribution. (a) The probability that x lies between 7 and 22 is (Round to three decimal places as needed.) (b) The probability that x lies between 8 and 25 is (Round to three decimal places as needed.) (c) The probability that x lies between 11 and 17 is (Round to three decimal places as needed.) (d) The probability that x lies between 5 and 13 is (Round to three decimal places as needed.)

For the probability distribution, find b. P(y> 2) c. F(y = 6) d. P(y = 6) 0.05, 0.10, f(y)= 0.15, 0.20, X, y = -2 y = -1 y = 0 y = 1 y = 2

Assume the geometric distribution applies. Use the given probability of success p to find the indicated probability.  Find P(5) when p= 0.90

Hour: 1. Let Y the number of siblings for a student at a local high school. Suppose we choose someone from the school at random. The probability distribution of Y is as Name: Date: follows. Y 2. 3. 4 5+ Probability 0.02 0.25 0.35 0.20 0.10 0.08 (a) Is Y a discrete or continuous? Explain. (b) Is this a valid probability distribution? Explain. (c) Create a histogram for the probability distribution and describe its shape. (d) Find the probability that the randomly selected student has at least one sibling. (e) Describe in words what P(Y>2) means and find the probability. (f) Calculate the mean of Y. Interpret this in context. (g) The standard deviation is 1.236. Interpret this in context. © 2017 BFW Publishers Starnes/Tabor Statistics and Probability with Applications 3/e
