Age of College Students Find the 80% confidence
intervals for the variance and standard deviation of the ages of
seniors at Oak Park College if a random sample of 23 students has a
standard deviation of 2.9 years. Assume the variable is normally
distributed. Use the chi-square distribution table to find any
chi-square values to three decimal places. Round the final answers
to one decimal place.
Mean=33,820.21 Standard Deviation=22,948.45 n=52 Calculate a 99% confidence interval, assuming that sigma is unknown.
