    The sample mean weights for two varieties of lettuce grown for 16 days in a controlled environment are 3.259 and 1.413 and the corresponding sample standard deviations are .400 and .220. If the sample sizes for the two varieties are 9 and 6 respectively, obtain a 95% confidence interval for the difference of the mean weights assuming that the two population standard deviations are equal. (Given: weight of each variety of lettuce is normally distributed)
