Tprint Cellular has introduced a new billing plan called "Your Choice." Under the plan, you choose your allotment of cell phone minutes at the beginning of each month. Your monthly bill is then a fixed charge of $10, plus 8 cents for each minute in your allotment. If you talk more than your allotted minutes in a month, you must pay a penalty charge of 40 cents per minute. If you do not use the minutes allotted to you in a month, the unused minutes are lost and do not "roll over" to the next month. From your cell phone bills the past 10 months, you find the following data on your minutes talked per month, and you decide to use this empirical distribution as a forecast of your talking behavior going forward. Assume that you will not alter your talking behavior based on your allotment of minutes. Month Minutes Feb 280 Jan 380 Dec 255 Nov 250 Oct Sep Aug Jul Jun May 190 315 250 350 275 260 (a) Your old plan offered 300 minutes for a fixed charge. What service level does an allotment of 300 minutes represent?
