For a new study conducted by a fitness magazine, 250 females were randomly selected. For each, the mean daily calorie consumption was calculated for a September-February period. A second sample of 210 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 2384.3 calories daily with a standard deviation of 192. During the March-August period, participants consumed a mean of 2415.7 calories daily with a standard deviation of 212.5. 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% confidence interval for u, -,, the difference between the mean daily calorie consumption , of females in September-February and the mean daily calorie consumption u, of females in March-August. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places. (If necessary, consult a list of formulas.) Lower limit: Upper limit: 0

For a new study conducted by a fitness magazine, 250 females were randomly selected. For each, the mean daily calorie consumption was calculated for a
September-February period. A second sample of 210 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 2384.3 calories daily with a standard deviation
of 192. During the March-August period, participants consumed a mean of 2415.7 calories daily with a standard deviation of 212.5. 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% confidence interval for µ, -H,, the difference between the mean daily calorie consumption u, of females in
September-February and the mean daily calorie consumption µ, of females in March-August. Then find the lower limit and upper limit of the 95% confidence
interval.
Carry your intermediate computations to at least three decimal places. Round your answers to at least two decimal places. (If necessary, consult a list of
formulas.)
