Kadesha is simplifying the expression below. Negative (x minus 3) minus 2 (x minus 1)

She lists the steps that she uses to simplify the expression as follows:

Step 1: Distribute –1 through (x minus 3), and distribute –2 through (x minus 1).
Step 2: Rewrite the expression as Negative x minus 3 minus 2 x minus 2.
Step 3: Combine –x and –2x, and combine –3 and –2.
Step 4: The simplified expression is Negative 3 x minus 5.

In which step did Kadesha make the first error?
A. She made the first error in Step 1 because only –2 should be distributed through the parentheses.

B. She made the first error in Step 2 because Step 2 should be Negative x + 3 minus 2 x + 2.

C. She made the first error in Step 3 because –x and –2x cannot be combined.

D. She made the first error in Step 4 because the simplified expression is Negative x minus 5.

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.
