The Chartered Financial Analyst (CFA) designation is fast becoming a requirement for serious investment professionals. It is anattractive alternative to getting an MBA for students wanting a career in investment. A student of finance is curious to know if a CFAdesignation is a more lucrative option than an MBA. He collects data on 36 recent CFAS with a mean salary of $145,000 and astandard deviation of $36,000. A sample of 47 MBAS results in a mean salary of $135,000 with a standard deviation of $24,000.Assume that H, is the population mean for individuals with a CFA designation and u, is the population mean of individuals with MBAS.(You may find it useful to reference the appropriate table: z table or t table)a. Set up the hypotheses to test if a CFA designation is more lucrative than an MBA at the 10% significance level.O Họ: 41- H2 = 0; HA: H1 - H2# 0O Ho: 1-4220; HA H1 - 42<0Ho: 1-H250; HA H1- 42>00b-1. Calculate the value of the test statistic. Do not assume that the population variances are equal. (Round all intermediatecalculations to at least 4 decimal places and final answer to 2 decimal places.)Test statistic

The accounting department analyzes the variance of the weekly unit costs reported by two production departments. A sample of 16 cost reports for each of the two departments shows cost variances of 2.3 and 5.4, respectively. Is this sample sufficient to conclude that the two production departments differ in terms of unit cost variance? Use ? = 0.10. State the null and alternative hypotheses. -H0: ?12 > ?22 Ha: ?12 ≤ ?22 -H0: ?12 ≠ ?22 Ha: ?12 = ?22 -H0: ?12 ≤ ?22 Ha: ?12 > ?22 -H0: ?12 = ?22 Ha: ?12 ≠ ?22 Find the value of the test statistic.

Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why?

At what level of significance is this a significant difference?
For each scenario below read the given null and alternative hypotheses statements as well as the initial decision about the null hypothesis. Post a conclusion about the claim in each test. (This means when you post your answer, you do not need to include any statement about the null hypothesis. Only the final conclusion is needed.) **Chart 1 is attached** 1 Winning team data were collected for teams in different spots. use a .05 level of significance to test the claim that home/visitor wins are independent of the sport. **Table 1 is attached** P-Value=0.762
