Question

Scenario 44 A job consists of three elements. Twenty observations for each element were timed, and the resulting data are shown in the following table. A performance rating factor has also been assigned for each element, as shown in the table. The job has an allowance of 20% of normal time. Element #1 #2 #3 Performance Rating 0%) 80 100 110 Average Element Time in minutes) 3.6 2.5 3.1 Use the information in Scenario 4.4. What is the normal time for the entire job? o a. Greater than or equal to 10.0 minutes o b.Less than 10.0 minutes but greater than or equal to 8.5 minutes o c. Less than 8.5 minutes but greater than or equal to 7.0 minutes d l ess than 7 minutes

Explanation / Answer

here normal time for an element =performance rating *average element time

hence normal time for entire job =3.6*0.8+2.5*1+3.1*1.1=8.79

option B is correct

( also std time =normal time/(1-allowance time) =8.79/(1-0.2)=10.99 which is greater than 10)
