A small-business Web site contains 100 pages and 60%, 30%, and 10% of the pages contain low, moderate, and highgraphic content, respectively. A sample of four pages is selected without replacement, and X and Y denote the numberof pages with moderate and high graphics output in the sample, respectively. What is the variance of Y given that thereare no pages with moderate graphics drawn? Express your answer up to three decimal places.• Compute the conditional probabilities of Y given X=0. Recall that P(A|B)P(ANB)andP(B)P(AN B) = fAB(A, B).Compute yfy|r=0)Compute the expected value of Y given x=0.Compute y² fy]æ=–0) and take the sum.Compute the variance of Y given X=1. Note that the 2nd term in the formula is the square of the conditional mean.

Two surfers and statistics students collected data on the number of days on which surfers surfed in the last month for 30 longboard (L) users and 30 shortboard (S) users. Treat these data as though they were from two independent random samples. Test the hypothesis that the mean days surfed for all longboarders is larger than the mean days surfed for all shortboarders (because longboards can go out in many different surfing conditions). Use a level of significance of 0.05. Longboard: 4,9,8,4,9,8,8,6,7,9,11,11,11,13,12,16,14,9,11,18,20,15,10,16,20,20,8,20,21,23 O Shortboard: 6,4,4,6,8,8,6,9,4,6,7,5,9,7,4,16,13,11,13,13,11,15,10,10,13,14,11,21,21,12 Determine the hypotheses for this test.

For a marketing class term project, Bob is investigating whether college seniors eat lessfrequently in fast-food chains than college freshmen. He asked 11 freshmen and 11 seniors tokeep track of how many times they ate in a fast-food restaurant during the month of October.Assuming equal variances, can you conclude that the mean is significantly smaller for collegeseniors at the 5 percent level of significance?Seniors Freshmen10 165 919 1615 145 1810 1018 198 1520 97 178 20
We are interested in determining whether or not the variances of the sales at two music stores (A and B) are equal.

The personality characteristics of business leaders (e.g., CEOS) are related to the operations of the businesses that they lead (Oreg & Berson, 2018). Traits like openness to experience are related to positive financial outcomes and other traits are related to negative financial outcomes for their businesses. Suppose that a board of directors is interested in evaluating the personality of their leadership. Among a sample of n = 16 managers, the sample mean of the openness to experiences dimension of personality was M = 4.50. Assuming that u = 4.24 and o = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with a = .05 to test the hypothesis that this company's business leaders' openness to experience is different from the population.
