**Consider the outcome of the roll of two fair dice. In this case, the sample space \( S \) consists of all pairs of numbers \((n, m)\) where \(1 \leq n \leq 6\) and \(1 \leq m \leq 6\). Each of the 36 points in the sample space have the same probability.****Give two different random variables defined on \( S \) that are equal in distribution.***(Hint: Don't make this problem harder than it is. I just want to see if you understand the concept of random variable.)*

(Problem for Questions 22- 25). In a study focusing on children on the autism spectrum a team of psychologists were interested in the distribution of the children on the spectrum. After having 100 children complete some tests, they categorized children as Low, Medium, High on the autism spectrum. They counted how many children were in each category and this is what they came up with: Low AS 44 Medium AS 30 High AS 26

Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna).† Suppose that in a remote part of the Grand Canyon, a random sample of six of these birds was caught, weighed, and released. The weights (in grams) were as follows. 3.7 2.9 3.8 4.2 4.8 3.1 The sample mean is x = 3.75 grams. Let x be a random variable representing weights of hummingbirds in this part of the Grand Canyon. We assume that x has a normal distribution and ? = 0.78 gram. Suppose it is known that for the population of all Anna's hummingbirds, the mean weight is ? = 4.60 grams. Do the data indicate that the mean weight of these birds in this part of the Grand Canyon is less than 4.60 grams? Use ? = 0.05. Compute the z value of the sample test statistic.
