Demand for walnut fudge ice cream at the Sweet Cream Dairy can be approximated by a normaldistribution with a mean of 21 gallons per week and a standard deviation of 3.5 gallons per week. Leadtime is two days, and the dairy is open seven days a week.Now an order is place when there is a supply of 8 gallons on hand. What is the probability of experiencinga stockout before this order arrives?0.14230.41680.58320.8577

Cell Phone Lifetimes A recent study of the lifetimes of cell phones found the average is 23.2 months. The standard deviation is 3.1 months. If a company provides its 33 employees with a cell phone, find the probability that the mean lifetime of these phones will be less than 23.8 months. Assume cell phone life is a normally distributed variable, the sample is taken from a large population, and the correction factor can be ignored. Use a TI-83 Plus/TI-84 Plus calculator. Round your answer to at least four decimal places. P(X<23.8)=
