MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER An artide in the San Jose Mercury News stated that students in the California State University system take 4.5 years, on average, to finish their undergraduate degrees. Suppose you believe that the mean time is longer. You canduct a survey of 44 students and obtain a sample mean or 5.1 with a sample standard deviation of 1.2. Do the data support your claim at the 1% level? of a Note: If you are using a student's t-distribution for the problem, you may assume that the underlying population is normally distributed.
