The Chartered Financial Analyst (CFA) designation is fast becoming a requirement for serious investment professionals. Although it requires a successful completion of three levels of grueling exams, it also entails promising careers with lucrative salaries. A student of finance is curious about the average salary of CFA charterholders in Toronto. He takes a random sample of 30 charterholders and computes a mean salary of $83,277 with a standard deviation of $5,473. Use this sample information to find a 90% confidence interval for the average salary of CFA charterholders in Toronto. Assume that the values are approximately normally distributed. Use t-distribution. Round to the nearest dollar.

For part (a) round your answer to 3 decimal places.

(a) What is the critical t-value that will need to be used to calculate the confidence interval?

For parts (b),(c), round your answer to the nearest dollar.

(b) What is the error

(c) What is the 90% confidence interval?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
