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 13 statistics students who were asked how many hours per unit they studied. Assume a normal distribution for the population.

NEED ANSWER FOR ALL PLEASE PLEASE PLEASE BOTH PICS ARE FOR ONE QUESTION
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 13 statistics students who were asked how many
hours per unit they studied. Assume a normal distribution for the population.
2.1, 2.5, 3.1, 1.7, 1, 2.2, 2, 2.9, 2.7, 3.2, 3.9, 0.6, 3.2
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
H1: ?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-value is ? a
f. Based on this, we should Select an answer
the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the population mean is not significantly more than 2 at a = 0.05, s0
there is sufficient evidence to conclude that the population mean study time per unit for
statistics students is equal to 2.
O 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.
