The average house has 13 paintings on its walls. Is the

What can be concluded at the αα = 0.05 level of significance?
- For this study, we should use Select an answer z-test for a population proportion t-test for a population mean
- The null and alternative hypotheses would be:
H0:H0: ? μ p Select an answer < ≠ > =
H1:H1: ? μ p Select an answer = > ≠ <
- The test statistic ? z t = (please show your answer to 3 decimal places.)
- The p-value = (Please show your answer to 4 decimal places.)
- The p-value is ? ≤ > αα
- Based on this, we should Select an answer fail to reject accept reject the null hypothesis.
- Thus, the final conclusion is that ...
- The data suggest the populaton mean is significantly different from 13 at αα = 0.05, so there is sufficient evidence to conclude that the population mean number of paintings that are in teachers' houses is different from 13.
- The data suggest that the population mean number of paintings that are in teachers' houses is not significantly different from 13 at αα = 0.05, so there is insufficient evidence to conclude that the population mean number of paintings that are in teachers' houses is different from 13.
- The data suggest the population mean is not significantly different from 13 at αα = 0.05, so there is sufficient evidence to conclude that the population mean number of paintings that are in teachers' houses is equal to 13.
