The partners at an investment firm want to know which of their two star financial planners, brayden or zoe, produced a higher population mean rate of return last quarter for their dients. the partners reviewed last quarters rates of return for random samples of clients who were managed by brayden or zoe. the mean rate of return for a sample of 30 of brayden's clients was 3.54% with a standard deviation of 0.92%. the mean rate of return for a sample of 30 of zoe's clients was 3.87% with a standard deviation of 2.08%. let be the population mean rate of return for brayden's clients and 2 be the population mean rate of return for zoe's clients. based on these results, the partners test the alternative hypothesis ha : μ 1-2 < 0, with α-: 0.05, assuming that the population standard deviations of the two groups are not equal and using 29 degrees of freedom. if the t-test statistic is t 0.79 and the rejection regions is less than to.01.699 what conclusion could be made about the population mean rate of return of the clients for zoe and brayden? ldentify all of the appropriate conclusions. select all that apply select all that apply reject the null hypothesis. fail to reject the null hypothesis. there is sufficient evidence at the α-0.05 level of significance to conclude that the population mean rate of return for brayden's clients last quarter is less than the population mean rate of return for zoe's clients 0.05 level of significance to conclude that the population mean rate of there is insufficient evidence at the return for brayden's clients last quarter is less than the population mean rate of return for zoe's clients
