Suppose a study reported that the average personn watched 3.37 hours of television per day. a random sample of 15 people gave the number of hours of television watched per day shown below. at the 1% significance level, do the data provide sufficent evidence to conclude that the amount of television watched per day last year by the average person is greater than the value reported in the study? 2.2, 4.0, 4.7, 4.8, 4.2, 5.8, 4.0, 5.5, 2.3, 3.4, 5.1, 5.6, 2.2, 4.1, 2.3 in constructing a 96% confidence interval for the parameter in this problem the proper value to use for the question is ? a. 0.8315 from the z chart table
