Question

Suppose Charlene Brewster has times​ (in seconds) of 8.4​, 8.6​, 8.3​, 8.5​, 8.7​, 8.5 and a performance rating of 110​%. The normal time for this operation​ = ____ seconds ​(round your response to two decimal​ places).
Based on the normal time and the observed times, Charlene's work performance should be rated as ____.

Answer 1

Answer:

8.5

Faster than Normal

Explanation:

Charlene Brewster normal time for the operation will be calculated by taking average of times.

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

= 8.5

The normal time will be calculate by dividing the Charlene Brewster time by performance rating

8.5 / 110% = 7.7

The Charlene work performance is rated as faster than the normal time.
