if charlene brewster has times of 8.4, 8.6, 8.3, 8.5, 8.7, and 8.5 and a performance rating of 110%, what is the normal time for this operation? is she faster or slower than normal? [px]



Answer :

Normal time taken for operation = 7.7

Charlene's work performance is faster than normal time.

Need to define Charlene's average time:

8.4 + 8.6 + 8.3 + 8.5 + 8.7 + 8.5)/6

Avg time taken= 8.5.

Performance rating = 110/100 = 1.1

normal time taken:  8.5/1.1

normal time taken= 7.7

hence, 8.5 [tex]\geq[/tex] 7.7

Charlene is faster than normal time.
