Question 29 A researcher is testing the hypothesis that a population mean is equal to zero. From a sample with 64 observations, the researcher calculates a sample mean of -2.5 and a sample standard deviation of 8.0. At which levels of significance should the researcher reject the hypothesis? 1% significance 5% significance 10% significance A) Reject Fail to reject Fail to reject B) Fail to reject Fail to reject Reject C) Reject Reject Reject D) Fail to reject Reject Reject Question 30 Trina Romel, mutual fund manager, is taking over a poor-performing fund from a colleague. Romel wants to calculate the return on the portfolio. Over the last five years, the fund’s annual percentage returns were: 25, 15, 12, -8, and –14. Determine if the geometric return of the fund will be less than or greater than the arithmetic return and calculate the fund’s geometric return: Geometric Return Geometric compared to Arithmetic A) 4.96% greater than B) 12.86% greater than C) 12.86% less than D) 4.96% less than
