One hundred forty-one of the 224 high school students surveyed at a local school say they plan on taking some form of postsecondary education. calculate the margin of error (me), rounded to the nearest tenth of a percent. is it reasonable that the state education department claims the percentage for the entire state is 68%? justify your answer.
a: yes, it is reasonable because the me is 5.6% and the population proportion of 68% falls within the sample interval of 62.9% ± 5.6%
b: no, it is not reasonable because the me is 3.2% and the population proportion of 68% falls outside the sample interval of 62.9% ± 3.2%
c: yes, it is reasonable because the me is 6.5% and the population proportion of 68% falls within the sample interval of 62.9% ± 6.5%
d: no, it is not reasonable because the me is 6.5% and the population proportion of 63% falls outside the sample interval of 68.0% ± 6.5%

the answers c

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!
