Iowa State University is interested in the hourly wages earned by their undergraduate students over the summer. It is known that the distribution of hourly wages for all undergraduates in the United States is roughly bell shaped. The university randomly samples 24 Iowa State students and compiles information about their summer jobs. The sample mean was $13.12/hr and the standard deviation was $1.05/hr for the sample collected by the University. The analysts intend to construct a confidence interval to estimate the mean hourly wages for Iowa State students.
Required:
Report here the UPPER BOUND of the most appropriate 90% confidence interval for this problem. Keep FOUR decimals in your intermediate calculations and report your final answer as a number, rounding to TWO decimal places.
