Thank you
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.
3.1, 0, 0, 1.3, 1.3, 0.6, 0, 2.9, 1.1, 3.1, 2.1, 0.6, 1.1, 2.3, 0.1
What can be condluded 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: ? v Select an answer v
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 ? v a
f. Based on this, we should Select an answer V 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 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.
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.
h. Interpret the p-value in the context of the study.
O There is a 1.69186863% chance that the population mean study time per unit for statistics
students is less than 2.
O There is a 1.69186863% chance of a Type I error.

O The data suggest the populaton mean is significantly less than 2 at a = 0.10, so there is
sufficient evidence to condude that the population mean study time per unit for statistics
students is less than 2.
h. Interpret the p-value in the context of the study.
O There is a 1.69186863% chance that the population mean study time per unit for statistics
students is less than 2.
O There is a 1.69186863% chance of a Type I error.
O If the population mean study time per unit for statistics students is 2 and if you survey
another 15 statistics students, then there would be a 1.69186863% chance that the sample
mean for these 15 statistics students would be less than 1.31.
O if the population mean study time per unit for statistics students is 2 and if you survey
another 15 statistics students, then there would be a 1.69186863% chance that the population
mean study time per unit for statistics students would be less than 2.
i. Interpret the level of significance in the context of the study.
O If the population mean study time per unit for statistics students is 2 and if you survey
another 15 statistics students, then there would be a 10% chance that we would end up falsely
concuding that the population mean study time per unit for statistics students is less than 2.
Oif the population mean study time per unit for statistics students is less than 2 and if you
survey another 15 statistics students, then there would be a 10% chance that we would end up
falsely concuding that the population mean study time per unit for statistics students is equal
to 2.
Q There is a 10% chance that the population mean study time per unit for statistics students is
less than 2.
O There is a 10% chance that students just don't study at all so there is no point to this survey.
