The human resources department of a major corporation announced that the number of people interviewed by the corporation in one month has a mean of 105 and a standard deviation, o, of 16. The management of the corporation suspects that the standard deviation exceeds 16. A random sample of 11 months yielded a mean of 108 interviews, with a standard deviation of 19. If we assume that the number of people interviewed by the corporation in one month follows an approximately normal distribution, is there enough evidence to conclude, at the 0.1 level of significance, that the management's claim is correct? Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) The null hypothesis: H. : The alternative hypothesis: H₁ 0² 19 The type of test statistic: (Choose one) The value of the test statistic: (Round to at least three decimal places.) 0 The p-value: (Round to at least three 0 decimal places.) Can we support the claim that the standard deviation of number of people interviewed by the corporation in one month exceeds 16?
