The average retirement age in America is 65 years old. Do small business owners retire at a younger average age? The data below shows the results of a survey of small business owners who have recently retired. Assume that the distribution of the population is normal. 60, 56, 70, 70, 72, 71, 72, 60, 59, 62, 56 What can be concluded at the the a = 0.10 level of significance level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho ? O Select an answer C H₁: ? € Select an answer C c. The test statistic ? C = d. The p-value = e. The p-value is ? ☺ a f. Based on this, we should g. Thus, the final conclusion is that ... O (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) Select an answer the null hypothesis. The data suggest the population mean retirement age for small business owners is not significantly younger than 65 at a = 0.10, so there is insufficient evidence to conclude that the population mean retirement age for small business owners is younger than 65. O The data suggest the population mean is not significantly younger than 65 at a = 0.10, so there is sufficient evidence to conclude that the population mean retirement age for small business owners is equal to 65. The data suggest the populaton mean is significantly younger than 65 at a = 0.10, so there is sufficient evidence to conclude that the population mean retirement age for small business owners is younger than 65.

Question
![The average retirement age in America is 65 years old. Do small business owners retire at a younger average
age? The data below shows the results of a survey of small business owners who have recently retired. Assume
that the distribution of the population is normal.
60, 56, 70, 70, 72, 71, 72, 60, 59, 62, 56
What can be concluded at the the a = 0.10 level of significance level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho ? O
Select an answer C
H₁ ? Select an answer
O
c. The test statistic ? C =
d. The p-value =
e. The p-value is ? a
f. Based on this, we should
g. Thus, the final conclusion is that ...
(please show your answer to 3 decimal places.)
(Please show your answer to 4 decimal places.)
Select an answer the null hypothesis.
The data suggest the population mean retirement age for small business owners is not
significantly younger than 65 at a = 0.10, so there is insufficient evidence to conclude that the
population mean retirement age for small business owners is younger than 65.
The data suggest the population mean is not significantly younger than 65 at a = 0.10, so there is
sufficient evidence to conclude that the population mean retirement age for small business
owners is equal to 65.
The data suggest the populaton mean is significantly younger than 65 at a = 0.10, so there is
sufficient evidence to conclude that the population mean retirement age for small business
owners is younger than 65.
