Suppose the coffee industry claimed that the average adult dn'nks 1.7 cups of coffee per day. To test this claim, a random sample of 60 adults was selected, and their average coffee consumption was found to be 1.85 cup-s per day. Assume the standard deviation of daily coffee consumption per day is 0.5 cups. Using a = 0.10, complete parts a and b beiow. a. Is the coffee industry's claim supported by this sample? Determine the null and alternative hypotheses. The ztest statistic is [:l. (Round to two decimal places as needed.) The critical zscore(s) is(are) |:| (Round to two decimal places as needed. Use a comma to separate answars as needed.) Because the test statistic the null hypothesis. b. Determine the p-value for this test. The pvalue is El. (Round to three decimal places as needed.)
