19.12 In Chapter 1, Table 1.1 lists the weights of 53 male statistics students. Although students were asked to report their weights to the nearest pound, inspection of Table 1.1 reveals that a disproportionately large number (27) reported weights end- ing in either a 0 or a 5. This suggests that many students probably reported their weights rounded to the nearest 5 or 10 pounds rather than to the nearest pound. Using the .05 level of significance, test the null...

Jessica knows that the adult population gets, on average, eight hours of sleep each night. A hypothesis test can help her see if college students are different from the adult population. Jessica tabulated that her sample of 101 students got an average of 6.9 hours of sleep each night, with a standard deviation of 2.5. Using the data provided and the formula below, what is the t-statistic that Jessica calculates? Answer choices are rounded to the hundredths place.
