A crossover trial is planned to evaluate the impact of an educational intervention program to reduce alcohol consumption in patients determined to be risk for alcohol problems. The plan is to measure alcohol consumption ( the number of drinks on a typical drinking day) before the intervention and then again after participants complete the educational intervention program. How many participants would be required to ensure that a 95% confidence interval for the mean difference in the number of drinks is within two drinks of the true mean? Assumed that the standard deviation of the difference in the mean number of drinks is 6.7 drinks.
This should be on excel format.
Determine the standard score for the value x=452 realative to its sample, where the sample mean is 500 and the standard deviation is 32.

Thirty homes responded, and the sample mean water use per day was 77 gallons with a standard deviation of 9.0 gallons per day.
The demand, D, on any given day is uniformly distributed over [80,140]. How many units should the retailer order to maximize expected profit?
Given this, compute the following probabilities for demand during lead time(DDLT).
