A market research firm used a sample of individuals to rate the purchase potential of a particular product before and after the individuals saw a new television commercial about the product. The purchase potential ratings were based on a 0 to 10 scale, with higher values indicating a higher purchase potential. The null hypothesis stated that the mean rating "after" would be less than or equal to the mean rating "before." Rejection of this hypothesis would show that the commercial improved the mean purchase potential rating. Use = .05 and the following data to test the hypothesis and comment on the value of the commercial.

5.15 The ends of the laminated-wood roof arch shown are
tied together with a horizontal steel rod 90 feet, "10 inches"
long, which must withstand a total load of 60 k. Two turn-
buckles are used. All threaded rod ends are upset.
a. Determine the required diameter D of the rod if
the maximum allowable stress is 20 ksi.
b. If the unstressed length of the rod is 90 feet,
"10 inches" and there are four threads per inch
on the upset ends, how many turns of one
turnbuckle will bring it back to its unstressed
length after it has elongated under full allowable
tensile stress? E = 29 × 103 ksi.
