Frank is investigating the numerical value of 2x · 2y when x and y are both integers. He makes the following two claims.
Claim 1: When x and y are both negative integers, the value of 2x · 2y is always a non–whole number. For example, 2–1 · 2–1 = 0.25 and 2–5 · 2–1 = 0.015625.
Claim 2: When only one of x or y is a negative integer, the value of 2x · 2y is always a non–whole number. For example, 22 · 2–3 = 0.5 and 2–5 · 21 = 0.0625.
Which statement correctly classifies Frank's claims?
A. Frank is correct in both Claim 1 and Claim 2 as both pairs of examples prove the given claims.
B. Frank is incorrect in both Claim 1 and Claim 2 since both pairs of examples are not sufficient to prove the given claims.
C. Frank is correct in Claim 1 but is incorrect in Claim 2 as the value of 2x · 2y can be a whole number when only one of x or y is negative.
D. Frank is incorrect in Claim 1 since the value of 2x · 2y is sometimes a whole number when x and y are both negative but is correct in Claim 2.

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
