The average house has 11 paintings on its walls. Is the mean larger for houses owned by teachers? The
data show the results of a survey of 11 teachers who were asked how many paintings they have in their
houses. Assume that the distribution of the population is normal. Round your mean and standard
deviation to three decimal places when doing these calculations.

What can be concluded at the a = 0.05 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
(please show your answer to 2 decimal places.)
d. The p-value =
(Please show your answer to 3 decimal places.)
e. The p-value is ? va
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that ...
