Question 5: What is the distribution of n X?

The lengths of your statistics class has a continuous uniform distribution between 46 minutes and 58 minutes. Let X be the length of a class in minutes. If one section is randomly selected, answer the following questions What is the distribution of X? What is the probability that the class is at most 55 minutes long? What is the probability that the class is less than 51 minutes or more than 56 minutes long?

in "a" the blank is "z" and "t" distribution

A researcher wanted to determine whether certain accidents were uniformly distributed over the days of the week. The data show the day of the week for n = 296 randomly selected accidents.

The following data are given to you to find out whether the distribution is platykurtic: N- 100, Eα-15, Σα)= 97, Σα-33, Σα-253 and common factor (9) -3.

There are 20 different pairs of shoes. Pick at random 10 shoes. Let X be the number of paired shoes, M be the number of shoes that are left-foot, N be the number of shoes that are right-foot.   (a)  Find the distribution of X. Show your problem-solving process (not just the final answer) with a few sentences of explanation and give the formula   (b)  Let Y = M – N. Give all possible values of Y. Find the distribution of Y. Show your problem-solving process (not just the final answer) with a few sentences of explanation and give the formula.   (c)  let Z = |Y|, compute E(X), Var(X), E(Z) and Var(Z). Show your problem-solving process (not just the answer), keep 2 decimal places for E(X) and E(Z), and use the approximate values for the calculations of Var(X) and Var(Z).
