1. Find 99% condence interval for variance and standard deviation of the weights of one- gallon container of motor oil if a sample of 14 countainer has a variance of 3.2 ounces (variance is given). 2. A sample of 28 oil changes shows the standard deviation for the waiting time is about 5.2 minutes. Find 95% confidence interval of the population standard deviation for the waiting time
