Question

According to a company's website, the top 15% of the candidates who take the entrance test will be called for an interview. You have just been called for an interview. The reported mean and standard deviation of the test scores are 70 and 7, respectively. What is the possible range for your test score if you assume that the scores are normally distributed? (Round "z" value and final answer to 2 decimal places.) Range and above 2. You are considering the risk-return profile of two mutual funds for investment. The relatively risky fund promises an expected return of 7.4% with a standard deviation of 13.5%. The relatively less risky fund promises an expected return and standard deviation of 3.8% and 7.7%, respectively. Assume that the returns are approximately normally distributed. Use Table 1. a-1. Calculate the probability of earning a negative return for each fund. (Round "z" value to 2 decimal places and final answer to 4 decimal places.) Probability Riskier fund Less risky fund b-1. Calculate the probability of earning a return above 8.3% for each fund. (Round "z" value to 2 decimal places and final answer to 4 decimal places.) Probability Riskier fund Less risky fund
