4. CWD Business systems maintains a successful Telecom sales department for Top up callcredit in which a clerk takes orders by telephone. If the clerk is occupied on one line,incoming phone calls to the department are answered automatically by an answeringmachine and asked to wait. As soon as the clerk is free, the party that has waited thelongest is transferred and answered first. Calls come in at a rate of about 15 per hour. Theclerk is capable of taking an order in an average of 3 minutes. Calls tend to follow aPoisson distribution, and service times tend to be exponential. The clerk is paid $15 perhour, but because of lost goodwill and sales, CWD loses about $30 per hour of customertime spent waiting for the clerk to take an order.Part BCWD is considering adding a second clerk to take calls. The store would pay that person thesame $15 per hour.Using appropriate formula for the multiple channel model, answer the following questions:wait for service (Pw)?g. What is the probability that there is exactly 2 customers in the systemh. Should it hire another clerk? Explain by showing the cost savings -

Given information: It is given that the phone calls come in a rate of about 15 per hour. The clerk…

To many people's chagrin, Rally's (a fast food restaurant) was closed last semester for quite a while due to renovations. Their fries are a particular favorite with their customers. Suppose Rally's decides to change to a new potato supplier in hopes of saving some money. The new supplier advertises the same pricing as the old supplier, but guarantees more usable potatoes per delivery. Suppose Rally's gives the new supplier a trail run to see if their claim holds. A.) Identify the null hypothesis for the 'test'. B.) Explain clearly what the type I and type II errors are in teh context of this problem.
Ryde is a new nonprofit van share service where the driver gets paid all of the generated revenue, minus operating costs. A Ryde customer requests a route and the Ryde application commits a van to take them (i.e. there is already one person waiting in the vehicle). Any additional customers who request the same route in the next five minutes are added as long as it has space. Each Ryde van can fit up to five passengers, and on average, each Ryde driver gets 2 requests every 5 minutes for a particular route (and all requests are assumed to be independent). The Ryde driver will make $13 for each passenger in the car (the per-passenger charge) minus $4 (the operating cost). How much does the Ryde driver expect to make from any single trip? Express your answer in dollars, but without the dollar sign (e.g., enter something like 43.21).
A typical high school student consumes 67.5 pounds of sugar per year. As part of a new nutrition plan, each member of a track team plans to lower the sugar he or she consumes by at least 30% for the coming year. Assuming each track member had consumed sugar at the level of a typical high school student and will adhere to this plan for the coming year, what is the maximum number of pounds of sugar to be consumed by each track team member in the coming year? 44 47 54 66
The Bulldog Electronics Company is currently producing a submarine detector for the Navy. The detector will be powered by one of three uranium fuel cells. The fuel cells are activated sequentially, as needed. The procedure is the following. When the detector is installed at the bottom of the ocean, one fuel cell is activated. When that fuel cell stops working, a second cell is automatically activated. When it stops working, the third cell is automatically activated. The time to failure of each cell has a normal distribution with a mean of 400~hours and a standard deviation of 100~hours. Also, the time to failure of an individual cell is independent of the time to failure of any other cell. 1.iWhat is the probability a cell lasts between 300~hours and 700~hours?

Each box of Healthy Crunch breakfast cereal contains a coupon entitling you to a free package of garden seeds. At the Healthy Crunch home office, they use the weight of incoming mail to determine how many of their employees are to be assigned to collecting coupons and mailing out seed packages on a given day. (Healthy Crunch has a policy of answering all its mail on the day it is received.) If the answer is a whole number, write a whole number. If it has one decimal place, write one decimal place. Otherwise, round off to two decimal places. If the answer is greater than 999, put a comma. a. Solve for Σx = Blank 1 b. Solve for Σy = Blank 2 c. Solve for Σx2 = Blank 3 d.
