A new sleeping pill is advertised that increases the daily sleep time of insomniacs by an average of2.8hours, with a variance of0.25.A government group is conducting an independent study on the new pill to see if thevariance, o,of increased sleep time is different from the advertised variance. The government group testsfiftandomly chosen insomniacs on the new pill. The insomniacs in the sample report having an average daily increase in2.8hours of sleep, with a variance of0.08. Is there sufficient evidence, at the level of significance of0.01, to reject the claim made in the ad?
