.133 Making glassware. In a process for manufac- turing glassware, glass stems are sealed by heating them in a flame. The temperature of the flame varies. Here is the distribution of the temperature X measured in degrees Celsius: Temperature 540° 545° 550° 555° 560° Probability 0.1 0.25 0.3 0.25 0.1

Suppose that we roll two fair six-sided dice and record the numbers showing as an ordered pair. Let Y denote the absolute value of the difference of the two numbers. Find E(Y). Select one: О а.35/18 O b. 35/6 O c. 0 d. 5/6 e. None of the other choices

A survey was taken on how much trust people place in the information they read on the Internet. Construct a categorical frequency distribution for the data. A trust in all that they read, M trust in most of whathey read, H trust in about one-half of what they read, S trust in a small portion of what they read. M H M S M M A M I H. H.

I need help solving d-f

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).
