Find the 98% confidence intervals for the variance and standard deviation of the ages of seniors at Oak Park College if a random sample of 28 students has a standard deviation of 2.4 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.  < σ2 <
