Suppose Rachel is searching for a new home. A report on the neighborhood she is interested in states that the average home size in the neighborhood is 2615 ft 2 with a standard deviation of 185 ft 2 . Rachel thinks that this report is inaccurate and that homes in this neighborhood are smaller than reported. She investigates the records of a random sample of 36 homes in the neighborhood and finds the average home size to be 2415 ft 2 . Which of the following are the correct null and alternative hypotheses? Null hypothesis H0:µ<2615 ft 2 H0:µ=2415 ft 2 H0:x⎯⎯⎯=2415 ft 2 H0:x⎯⎯⎯<2615 ft 2 H0:µ=2615 ft 2 H0:x⎯⎯⎯=2615 ft 2 Alternative hypothesis H1:x⎯⎯⎯≠2615 ft 2 H1:µ≠2615 ft 2 H1:x⎯⎯⎯<2415 ft 2 H1:x⎯⎯⎯<2615 ft 2 H1:µ<2615 ft 2 H1:µ<2415 ft

step-by-step explanation:

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!
