#388: A school newspaper reporter decides to randomly survey 13 students to see if theywill attend Tet (Vietnamese New Year) festivities this year. Based on past years, sheknows that 19% of students attend Tet festivities. We are interested in the number ofstudents who will attend the festivities. (Bold #'s are randomized.)a. In words, define the Random Variable X.b. List the values that X may take on.(List every single value in order; Separate the answers with commas. NO SPACES.)c. Give the distribution of X: X.d.

Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna).t 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 a- 0.90 gram. Suppose it is known that for the population of all Anna's hummingbirds, the mean weight is u= 4.70 grams. Do the data indicate that the mean weight of these birds in this part of the Grand Canyon is less than 4.70 grams? Use a- 0.05. (a) What is the level of significance? State the null and alternate hypotheses. Will you use a left-tailed, right-tailed, or two-tailed test?

Assume that two dependent samples have been randomly selected from normally distributed populations. A test of abstract reasoning is given to a random sample of students before and after they completed a formal logic course. The results are given below. Before 74 80 72 80 80 67 93 85 91 77 After 73 80 70 83 78 68 90 82 87 75 Provide a 90% CI on the difference. Round your answers to 3 decimals. Provide negative signs when appropriate. Use leading zeros for values less than 1. Lower Limit: Upper Limit: Based on the results of your CI, what is the conclusion to a two-tailed hypothesis test at alpha = .10? Reject Ho / Do Not Reject Ho Do the results suggest there is a difference in means at alpha = .10? Yes / No
