Assume both follow a Normal distribution. What can be concluded at the the a = 0.05 level of significance
level of significance?
For this study, we should use Select an answer
a. The null and alternative hypotheses would be:
Ho: Select an answer
Select an answer
Select an answer v (please enter a decimal)
H: Select an answer V
Select an answer V
Select an answer V
(Please enter a decimal)
b. The test statistic ? v=
(please show your answer to 3 decimal places.)
c. The p-value =
d. The p-value is ?va
(Please show your answer to 4 decimal places.)
e. Based on this, we should Select an answer
| the null hypothesis.
f. Thus, the final conclusion is that ...
O The results are statistically insignificant at a = 0.05, so there is statistically significant
evidence to conclude that the population mean time in the shower for the poor is equal to the
population mean time in the shower for the rich.
O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude
that the population mean time in the shower for the poor is less than the population mean
time in the shower for the rich.
O The results are statistically insignificant at a = 0.05, so there is insufficient evidence to
conclude that the population mean time in the shower for the poor is less than the population
mean time in the shower for the rich.
O The results are statistically significant at a = 0.05, so there is sufficient evidence to conclude
that the mean time in the shower for the ten poor people that were surveyed is less than the
mean time in the shower for the thirteen rich people that were surveyed.
