A company manufacturing computer chips finds that 8% of all chips manufactured are defective. In an effort to decrease the percentage of defective chips, management decides to provide additional training to those employees hired within the last year. After training was implemented, a sample of 450 chips revealed only 27 defects. A hypothesis test is performed to determine if the additional training was effective in lowering the defect rate. Suppose the P-value associated with the test statistic is 0.0594. For a=.01, what is the correct conclusion?

a) The additional training did affect the defect rate.

b) The additional training significantly lowered the defect rate.

c) The additional training significantly increased the defect rate.

d) The additional training did not significantly lower the defect rate.

e) None of these.
