A job, consisting of four elements, was randomly observed five times for a time study. The following table shows the results (figures are in seconds):

Work Elements Observations Performance Rating
1. Prepare patty 40 41 50 48 36 0.8
2. Cook first side 78 81 77 89 83 1.1
3. Flip, press, cook the other side 54 55 59 58 63 1.3
4. Assemble 28 24 27 26 32 0.9

A. What is the Normal Time (in seconds) for each work element?
B. What is the Standard Time (in seconds) for the job if there is a 20% of the job time allowance for personal needs and unavoidable work delays?

Solution Preview

A. Normal Time = Average(Observation) * Performance Rating
B. Standard Time = Normal Time * (1+0.2)

Solution Summary

The following posting helps answer questions about normal time and standard time.

Peter Rourke, a loan processor at Wentworth Bank, has been timed performing four work elements, with the results shown in the following table. The allowances for tasks such as tis are personal. 7%; fatigue, 10%; and delay, 3%

Upload speed are measured on a standard scale I which the target value is 1.0. Data collected over the past year indicate that the upload speeds are approximately normally distributed with a means of 1.005 and a standard deviation of 0.10. Each day at 25 random times , the upload speed is measured . Assuming that the distribu

A normal distribution has a mean of 500 and a standard deviation of 50. A manager wants to simulate 2 values from this distribution, and has drawn these random numbers: -0.6 and 1.4. What are the 2 values respectively?

Assume that x has a normal distribution, with the specified mean and standard deviation. Find the indicated probabilities.
6)P(40 less than or equal to x less than or equal to 47); u = 50; o = 15
10) P( x greater than or equal to 2); u = 3; o = 0.25
Find the z value described and sketch the area described.

In an attempt to increase productivity and reduce costs, Pho Shigma Corporation is planning to install an incentive pay plan in its manufacturing plant. In developing standards for one operation, time-study analysts observed a worker for 30 minutes. During that time the worker completed 42 parts. The analysts rated the worker as

The amount of cereal in a box is not constant, but the distribution can be modeled with a normal distribution with a mean of 16.5 ounces. If the manufacturer is required to fill 90% of the containers with 16 (or more) ounces of cereal, what is the largest allowable value of the standard deviation ?

1. For a standardized normal distribution calculate the following probabilities
a. P(0.00 < z < or equal to 2.33)
b. P( -1.00 < z < or equal to 1.00)
c. P( 1.78 < z < 2.34).
2. A random variable is normally distributed with mean of 25 and standard deviation of 5. If an observation is randomly selected
a. what val
