A manufacturer wanted to know if more coupons would be redeemed if they were mailed to the female in the household rather than the male in the household. A coupon book was sent at random to either the male or female in a random sample of 50 male-female households. A month later, a coupon book was sent to the other member of the pair. The manufacturer found that the mean difference (female – male) in the number of coupons redeemed was 1.5 with a standard deviation of 4.75. Do these data provide convincing evidence that the mean number of coupons redeemed is greater when the coupons were addressed to a female? Use a = 0.01.

Question
A manufacturer wanted to know if more coupons would be redeemed if they were mailed to the female in
the household rather than the male in the household. A coupon book was sent at random to either the male
or female in a random sample of 50 male-female households. A month later, a coupon book was sent to the
other member of the pair. The manufacturer found that the mean difference (female – male) in the number
of coupons redeemed was 1.5 with a standard deviation of 4.75.
Do these data provide convincing evidence that the mean number of coupons redeemed is greater when the
coupons were addressed to a female? Use a = 0.01.
