A grocery store claims that customers spend an average of 5 minutes waiting for service at the store's deli counter. A random sample of 40 customers was timed at the deli counter, and the average service time was found to be 5.6 minutes. Assume the standard deviation is 1.5 minutes per customer. Using alphaequals0.10, complete parts a and b below. a. Does this sample provide enough evidence to counter the claim made by the store's management? Determine the null and alternative hypotheses.

answer: the answer is simply nothing.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

no its the same as every other grade
