On average, Americans have lived in 2 places by the time they are 18 years old. Is this average more for college students? The 66 randomly selected college students who answered the survey question had lived in an average of 2.08 places by the time they were 18 years old. The standard deviation for the survey group was 0.5. 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: Но: ? v Select an answer v Hj: |?v| Select an answer v c. The test statistic ? v = (please show your answer to 3 decimal places.)

h. Interpret the p-value in the context of the study.
O There is a 9.91222659% chance that the population mean number of places that college
students lived in by the time they were 18 years old is greater than 2.
O If the population mean number of places that college students lived in by the time they were
18 years old is 2 and if you survey another 66 college students then there would be a
9.91222659% chance that the population mean number of places that these college students
lived in by the time they were 18 years old would be greater than 2.
O If the population mean number of places that college students lived in by the time they were
18 years old is 2 and if you survey another 66 college students then there would be a
9.91222659% chance that the sample mean for these 66 college students would be greater than
2.08.
There is a 9.91222659% chance of a Type I error.
i. Interpret the level of significance in the context of the study.
O If the population mean number of places that college students lived in by the time they were
18 years old is more than 2 and if you survey another 66 college students, then there would be
a 10% chance that we would end up falsely concluding that the population mean number of
places that college students lived in by the time they were 18 years old is equal to 2.
There is a 10% chance that the population mean number of places that college students lived
in by the time they were 18 years old is more than 2.
O There is a 10% chance that none of this is real since you have been hooked up to virtual reality
since you were born.
O If the population mean number of places that college students lived in by the time they were
18 years old is 2 and if you survey another 66 college students, then there would be a 10%

On average, Americans have lived in 2 places by the time they are 18 years old. Is this average more for
college students? The 66 randomly selected college students who answered the survey question had lived in
an average of 2.08 places by the time they were 18 years old. The standard deviation for the survey group
was 0.5. 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:
Но:
? v Select an answer v
H1:
? v| Select 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.)
%3D
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 ...
The data suggest that the populaton mean is significantly more 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 more than 2.
%3D
O The data suggest that the population mean is not significantly more than 2 at a = 0.10, so
there is statistically insignificant evidence to conclude that the population mean number of
places that college students lived in by the time they were 18 years old is more than 2.
The data suggest that the sample mean is not significantly more 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 more than 2.08.
h. Interpret the p-value in the context of the study.
