HW Problem 32.
;The average workweek in the US is down to 35 hours for
various reasons. Suppose this figure was obtained from a random sample of 20
employees and that the standard deviation of the sample was 4.3 hours. Use this
sample data to construct a 98% confidence interval for the population variance of
the number of hours worked per week for a worker. Round to four quality
decimal places and be sure to interpret your confidence interval.
