Location is known to affect the number, of a particular item, sold by heb pantry. two different locations, a and b, are selected on an experimental basis. location a was observed for 18 days and location b was observed for 13 days. the number of the particular items sold per day was recorded for each location. on average, location a sold 39 of these items with a sample standard deviation of 8 and location b sold 49 of these items with a sample standard deviation of 4. select a 99% confidence interval for the difference in the true means of items sold at location a and b. a) o [-1242,-7582]
b) o132.76, 45.24]
c)。8 1.76, 94.24]
d) 0-1 6.03,-3.97]
e)。[42.76, 55.24]
f. none of the above

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!
