Please answer: D- F

For letter E: The p-value is > or  ≤ 

For Letter F: reject or fail to reject or accept the null hypothesis 

 

On average, Americans have lived in 2 places by the time they are 18 years old. Is this average less for
college students? The 67 randomly selected college students who answered the survey question had lived in
an average of 1.99 places by the time they were 18 years old. The standard deviation for the survey group
was 0.3. What can be concluded at the a = 0.10 level of significance?
a. For this study, we should use t-test for a population mean
b. The null and alternative hypotheses would be:

) the null hypothesis.
O The data suggest that the populaton mean is significantly less than 2 at a = 0.10, so there is
statistically significant evidence to conclude that the population mean number of places that
college students lived in by the time they were 18 years old is less than 2.
O The data suggest that the sample mean is not significantly less than 2 at a = 0.10, so there is
statistically insignificant evidence to conclude that the sample mean number of places that
college students lived in by the time they were 18 years old is less than 1.99.
O The data suggest that the population mean is not significantly less than 2 at a = 0.10, so there
is statistically insignificant evidence to conclude that the population mean number of places
