Assume that a sample of 100 individuals resulted in a mean of 2.75 cups of coffee per day and that a sample of 250 men over the age of 18 has a mean weight of 201 lbs. Use the alternative hypothesis (H1) to help you write the problem to be computed in probability notation as we did in class, for each scenario. This following is known about the the populations and is NOT based on a sample. The true s. d. of cups of coffees consumed per day is 1.5 and the true s. d. of weight is 30 lbs. Test the hypotheses you wrote for the pre-class assignment using a 5% level of significance. Decide whether to reject the null in each case. In your owns words, explain what conclusion we can draw based on the test.

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
