The India Fund, Inc. (IFN) is a close-ended equity mutual fund launched by the Blackstone Groups Asset Management arm. Although it promises impressive returns, it does so at the cost of greater risk. An analyst would like to test if the variance of the returns for IFN is greater than 1400(%)2. He uses the following annual return data (in percent) to test his claim at the 1% level of significance, is the variance of returns greater than 1400(%)2? 2. Find the value x for which (Round your answer to 3 decimal places.) 2 a. ??(??17 ? ??) = 0.100 2 b. ??(??17 ? ??) = 0.900 2 c. ??(??17 < ??) = 0.100 2 d. ??(??17 < ??) = 0.900 3. Consider the following hypotheses: ??0 : ?? 2 = 165 ???? : ?? 2 ? 165 Find the p-value based on the following sample information, where the sample is drawn from a normally distributed population. a. ?? 2 = 257; ?? = 17 b. ?? 2 = 77; ?? = 17 c. Which of the above sample information enables us to reject the null hypothesis at ?? = 0.05? ?? 2 = 257; ?? = 17 A. Do not reject the null hypothesis, the population variance does not differ from 165. B. Pace University MAT 117 Statistical Inference Concerning Variance Questions Do not reject the null hypothesis, the population variance differs from 165. C. Reject the null hypothesis, the population variance differs from 165. D. Reject the null hypothesis, the population variance does not differ from 165. 2 ?? = 77; ?? = 17 A. Reject the null hypothesis, the population variance differs from 165. B. Do not reject the null hypothesis, the population variance differs from 165. C. Reject the null hypothesis, the population variance does not differ from 165. D. Do not reject the null hypothesis, the population variance does not differ from 165. 4. Find the value x for which: (Round your answers to 2 decimal places.) a. ??(??(8,23) ? ??) = 0.025 b. ??(??(8,23) ? ??) = 0.050 c. ??(??(8,23) < ??) = 0.025 d. ??(??(8,23) < ??) = 0.050 5. Construct the 98% interval estimate for the ratio of the population variances using the following results from two independently drawn samples from normally distributed population. (Round F value and final answers to 2 decimal places.) 6. Consider the following competing hypotheses and relevant summary statistics: Assume that the two populations are normally distributed. Do you reject the null hypothesis at the 10% significance level?  Get a 10 % discount on an order above \$ 100 Use the following coupon code : NURSING10
