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 t-test for a population mean b. The null and alternative hypotheses would be: Ho: e 65 H: < 65 c. The test statistic t = -0.321 (please show your answer to 3 decimal places.) d. The p-value = e. The p-value is ? Ba (Please show your answer to 4 decimal places.) f. Based on this, we should Select an answer the null hypothesis. g. Thus, the final conclusion is that ... 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.
