For a new study conducted by a fitness magazine, 260females were randomly selected. For each, the mean daily calorie consumption was calculated for aSeptember-February period. A second sample of 225 females was chosen independently of the first. For each of them, the mean daily calorie consumption was calculated for a March-August period. During the September-February period, participants consumed a mean of 2384.2 calories daily with a standard deviation of 170. During the March-August period, participants consumed a mean of 2415.8 calories daily with a standard deviation of 240. The population standard deviations of daily calories consumed for females in the two periods can be estimated using the sample standard deviations, as the samples that were used to compute them were quite large. Construct a 95%H1 -H2 for , the difference between the mean daily calorie consumption H1of females in September-February and the mean daily calorie consumption H2 of females in March-August. Then complete the table below.

What is the lower limit of the 95% confidence interval?

What is the upper limit of the 95% confidence interval?
