According to the Carnegie unit system, the recommended number of hours students should study
per unit is 2. Are statistics students' study hours less than the recommended number of hours per
unit? The data show the results of a survey of 13 statistics students who were asked how many
hours per unit they studied. Assume a normal distribution for the population.
1.7, 1, 2.3, 2.5, 2.5, 1.7, 0.7, 1.3, 3, 1, 0.9, 3, 0.6
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: ?v Select an answer v
H: ?v Select an answer v
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-valu is ? v a
f. Based on this, we should| Solect an answer v the null hypothesis.
