Two samples each of size 25 are taken from independent populations assumed to be normally distributed with equal variances. The first sample has a mean of 35.5 and standard deviation of 3.0 while the second sample has a mean of 33.0 and standard deviation of 4.0. What is the 99% confidence interval estimate for the difference in the two means? O a.-0.1822 to 5.1822 Ob -0.3822 to 5.1822 O c.-0.1822 to 7.1822 O d. -0.0822 to 4.1822 O e.-6.1822 to 5.1822
