Question
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 15 statistics students who were asked how many hours per unit they studied.
Assume a normal distribution for the population.
0, 1.9, 0.2, 2.1, 0, 2.4, 1.5, 2.6, 0, 3.4, 2.5, 0.1, 2.7, 2.7, 1.1
What can be concluded at the a = 0.10 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho: ?vSelect an answerv
H1: ?vSelect an answerv
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 answerv the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the population mean is not significantly less than 2 at a = 0.10, 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 the populaton mean is significantly less than 2 at a = 0.10, so there is
sufficient evidence to conclude that the population mean study time per unit for statistics
students is less than 2.
O The data suggest that the population mean study time per unit for statistics students is not
significantly less than 2 at a = 0.10, so there is insufficient evidence to conclude that the
population mean study time per unit for statistics students is less than 2.
