ourses/19615/assignments/491773?module_item_id=1411613 According to the Carnegie unit system, the recommended number of hours students should study per unit is 2. Are statistics students' study hours more than the recommended number of hours per unit? The data show the results of a survey of 12 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population. 3.7, 0.6, 2.5, 2.8, 1, 3, 1.2, 4.3, 2, 1.9, 1.2, 1 What can be concluded at the a = 0.05 level of significance? a. For this study, we should use |Select an answer b. The null and alternative hypotheses would be: Ho: 2v Select an answer H1: 2 Select an answer C. The test statistic ?v = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ?v a f. Based on this, we should | Select an answery the null hypothesis. g. Thus, the final conclusion is that ... The data suggest the populaton mean is significantly more than 2 at a = 0.05, so there is sufficient evidence to conclude that the population mean study time per unit for statistics students is more than 2.* The data suggest the population mean is not significantly more than 2 at a = 0.05, so there is sufficient evidence to conclude that the population mean study time per unit for statistics students is equal to 2. The data suggest that the population mean study time per unit for statistics students is not significantly more than 2 at a = 0.05, so there is insufficient evidence to conclude that the population mean study time per unit for statistics students is more than 2. h. Interpret the p-value in the context of the study. If the population mean study time per unit for statistics students is 2 and if you survey another 12 statistics students then there would be a 38.68589617% chance that the sample mean for these 12 statistics students would be greater than 2. 1. If the population mean study time per unit for statistics students is 2 and if you survey another 12 statistics students then there would be a 38.68589617% chance that the population mean study time per unit for statistics students would be greater than 2. There is a 38.68589617% chance that the population mean study time per unit for statistics students is greater than 2. O There is a 38.68589617% chance of a Type Lerror. i. Interpret the level of significance in the context of the study. If the population mean study time per unit for statistics students is more than 2 and if you survey another 12 statistics students, then there would be a 5% chance. that we would end up falsely concuding that the population mean study time per unit for statistics students is equal to 2. There is a 5% chance that the population mean study time per unit for statistics students is more than 2
