University of Jordan Name: Seat No.: 0198026 Faculty of Business Department of Finance ID No.: Research Methods in Finance Module. Final Exam PART ONE: True and False Questions 1. In 2019, the return on Stock G has a mean of 8.4% with a standard deviation of 2.1%. The return on Stock F has a mean of 3.6% with a standard deviation of 0.9%. Stock G has smaller relative variation than Stock F T 2. The sample covariance may never be negative 3. If all possible random samples are taken from a population, and the sample mean is computed, then the sample's mean is more than the population mean F 4. The central limit theorem assumes that as the sample size increases, the distribution of mean's population approximate the normal distribution t 5. Other things being equal, the margin of error of a confidence interval increases as the sample mean increases I 6. Using a significance level of 0.01 a confidence interval for a population mean is computed to be 0.65 to 0.75. If the level of significance is decreased, the interval for the population proportion becomes wider PART TWO: Multiple Choices Questions 1. Assume you are given that the mean return on assets for a specific project was 7.8% with a standard deviation of 2.3. Moreover, the distribution of means is bell-shaped. We should anticipate that 95 percent of all of these assets had a mean between? A) 5.5% and 10.1% 30% and 15% 3.2% and 12.4% D) 0.9% and 14.7% 2. The commission sales manager of A&B Company has gathered data on the number of products sold per month for the last 5 years. That data is given below: # of products 0 1 # of months 2 6 2 3 4 5 6 9 13 21 7 2 What is the weighted mean number of products per month? 3.31 B) 3.23 C) 3.54 D) 3.62 3. The median values of the following figures: 12, 32 48, 8, 22, 9, 30, and 18 is? A) 20 B22 C) 24 D) 26 4. The chairman of finance department has recorded the number of research papers citations issued per day by each of the 10 academic doctors in his department. The data were: 13, 21, 12, 34, 31, 13, 22, 26, 25, and 23. What is the first quartiles of the number of citations issued per day? A) 22.0 B) 22.5 C) 27.25 None of the above.
