Question 2A store stocks four alarm clock radios. If it has fewer than four clock radios available at the endof a week, the store restocks the item to bring the in-stock level up to four. If weekly demand isgreater than the four units in stock, the store loses the sale. The radio sells for $25 and costs thestore $15. The store manager estimates that the probability distribution of weekly demand for theradio is as follows:x(Weekly Demand)Probability00.0510.0520.130.240.450.160.0570.05a. What is the expected weekly demand for the alarm clock radio?b. What is the variance and standard deviation of weekly demand for the alarm clock radio?c. What is the probability that weekly demand will be greater than the number of availableradios?d. What is the expected weekly profit from the sale of the alarm clock radio? (Remember: Thereare only four clock radios available in any week to meet demand.)e. On average, how much profit is lost each week because the radio is not available whendemanded?

HCC builds 3 and 4-unit apartment buildings for investors and it is believed that the total construction time in days follow a normal distribution. With improvements in construction technology, the mean time to construct a triplex was reduced from 100 days to 80 days, however the standard deviation increased from 20 to 25 days. Failure to complete the triplex in 125 days still results in severe penalty fees. After these technological improvements have been implemented by HCC, answer the following questions: a. What is the probability of HCC not violating the contract and what is the probability of HCC violating the contract?
