Bonny's truck has a fuel tank which holds 50 gallons, and she typically drives 425 miles on a full tank. she has added a second tank, which holds 30 gallons. to figure how far she can go between fill-ups now, she multiplies 50 x 425, then divides by 30, to get 708.3 miles. is this correct?
a) yes.
b) no; she should have multiplied 425 by 30 + 50.
c) no; she should have divided 425 by 50, then multiplied by 80.
d) no; she should have divided 50 by 30, then multiplied that by 425.

Arecent study focused on the number of times men and women who live alone buy take-out dinner in a month. assume that the distributions follow the normal probability distribution and the population standard deviations are equal. the information is summarized below. statistic men women sample mean 24.85 21.33 sample standard deviation 5.54 4.93 sample size 34 36 at the 0.01 significance level, is there a difference in the mean number of times men and women order take-out dinners in a month? state the decision rule for 0.01 significance level: h0: μmen= μwomen h1: μmen ≠ μwomen. (negative amounts should be indicated by a minus sign. round your answers to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? what is the p-value? (round your answer to 3 decimal places.)
