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 16 statistics students who were asked how many hours per unit they
studied. Assume
normal distribution for the population.
1.8, 4.1, 0.8, 1.8, 4.1, 4.1, 4, 2.6, 0.6, 1, 3.1, 2.2, 3.1, 2.6, 1.4, 4.5
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:
Но: 2
Select an answer
H: ? vSelect 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 ? va
f. Based on this, we should Select an answer
g. Thus, the final conclusion is that ...
the null hypothesis.
O 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.
O The data suggest that the population mean study time
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.
unit for statistics students is not
O 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.
