normal time = observed time * performace rating
=15 * (1-0.198)
= 12.03
standard time = normal time * 1 / (1 -allowance factor ))
= 12.03 * (1/ (1 - 0.323))
= 17.76957
= 17.8

A methods and measurement analyst wants to develop a time standard for a certain task. In a preliminary study, he observed one worker perform the task six times with an average observed time of 25 seconds and a standard deviation of 3.8 seconds. What is the standard time for this task if the employee worked at a 15.2 percent faster pace than average, and an allowance of 20.6 percent of the workday is used? (Keep one decimal place in your...

In a time study of a manufacturing operation, 15 actual times were recorded for the duration of producing a product for a skilled worker who has an experience of 10 years and for an unskilled worker who started to work one months ago: For the skilled worker, the average time observed to complete a product was 12 minutes. The performance rating applied to the observed worker was 1.10 and the allowance during a 10-hour shift was 30% or 180 minutes....
The time necessary to complete a certain assembly-line task varies according to many factors: fatigue or freshness, worker skill, whether the required parts are available promptly, and so forth. Suppose that this variation may be adequately modeled using a normal distribution with mean 15 minutes and standard deviation 2 minutes. The quickest 5% of the assembly times are to be rewarded. How fast must an assembly be performed in order to be rewarded? 11.71 minutes 1.50 minutes 10.34 minutes 12.92 minutes...
A study of the time required for airplanes to land at a certain airport shows that the mean is 280 seconds with a standard deviation of 20 seconds. (The times are NOT normally distributed.) a) Find the mean and standard deviation of the sample mean for samples of size 36 . μ ¯ x = σ ¯ x = (Write your answer as a decimal, rounded to 2 decimal places.) b) For samples of size 36 , find the percentage...
