A worker-machine operation was found to involve 3.3 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. The worker’s time averaged 1.9 minutes per cycle, and the worker was given a rating of 120 percent (machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 12 percent of work time, determine the standard time for this job.

Answers

Answer 1

The standard time for this job will be "5.89 minutes". A further solution is provided below.

Given values are:

Machine time per cycle = 3.3 minutesPerformance rating = 100%Average cycle time = 1.9 minutesPerformance rating = 120%Allowance factor = 12% or 0.12

For machine,

→  The normal time will be:

= [tex]Average \ observed \ time\times Performance \ rating[/tex]

By substituting the values, we get

= [tex]3.3\times \frac{100}{100}[/tex]

= [tex]3.3 \ minutes[/tex]

When there is no allowance then the allowance factor will be zero (0).

→  The standard time will be:

= [tex]\frac{Normal \ time}{1-Allowance \ factor}[/tex]

= [tex]\frac{3.3}{1-0}[/tex]

= [tex]3.3 \ minutes[/tex]

For workers,

→  The normal time will be:

= [tex]Average \ observed \ time\times Performance \ rating[/tex]

= [tex]1.9\times \frac{120}{100}[/tex]

= [tex]2.28 \ minutes[/tex]

→  The standard time will be:

= [tex]\frac{Normal \ time}{1-Allowance \ factor}[/tex]

= [tex]\frac{2.28}{1-0.12}[/tex]

= [tex]2.59 \ minutes[/tex]

hence,

→  The standard time for this job will be:

= [tex]Standard \ time \ of \ machine+Standard \ time \ of \ worker[/tex]

= [tex]3.3+2.59[/tex]

= [tex]5.89 \ minutes[/tex]

Thus the above answer is correct.

Psychology is considered a science because it uses a systematic method of asking and answering problems, and it attempts to develop solutions to psychological problems.

Average age in a population. Suppose the 100-vector x represents the distribution of ages in some population of people, with xi being the number of i−1 year olds, for i = 1, . . . , 100. (You can assume that x 6= 0, and that there is no one in the population over age 99.) Find expressions, using vector notation, for the following quantities. (a) The total number of people in the population. (b) The total number of people in the population age 65 and over. (c) The average age of the population.

Average age in a population. Suppose the 100-vector x represents the distribution of ages in some population of people, with xi being the number of i−1 year olds, for i = 1, . . . , 100. (You can assume that x 6= 0, and that there is no one in the population over age 99.) Find expressions, using vector notation, for the following quantities. (a) The total number of people in the population. (b) The total number of people in the population age 65 and over. (c) The average age of the population. (You can use ordinary division of numbers in your expression.) (d) Does an unbiased estimate for the average age of the population exist?

(a) We can just add up all the xi and get 100 x −1. (b) Let's suppose we want to find y, such that \frac{y}{100} is an unbiased estimate for \frac{\sum_{i=1}^{100}x_i}{100}. Then \frac{y}{100} = \frac{\sum_{i=1}^{100}x_i}{100}. Let's now plug in 100 x −1 for \sum_{i=1}^{100}x_i. This means y = \frac{99 x −1}{100}. (c) Recall that the average of a vector is 0 x + 1. Then the average age of the population is 0(100 − 1) + 1 = 50. (d) No, because \frac{y}{100} ≠ \frac{\sum_{i=1}^{100}x_i}{100}.

50 People are 65 and over

The number of people who are 65 and older is 50 x − 1 = 45.

I think this may be either (b) or (c). An unbiased estimate for the average age of the population exists because \frac{y}{100} ≠ \frac{\sum_{i=1}^{100}x_i}{100}. An unbiased estimate is \frac{99 x −1}{100}.

(c) Recall that the average of a vector is 0 x + 1. Then the average age of the population is 50. (b) Let's suppose we want to find y, such that \frac{y}{100} is an unbiased estimate for \frac{\sum_{i=1}^{100}x_i}{100}. Then \frac{y}{100} = \frac{\sum_{i=1}^{100}x_i}{100}. Let's now plug in 100 x −1 for \sum_{i=1}^{100}x_i. This means y = \frac{99 x −1}{100}. (d) No, because \frac{y}{100} ≠ \frac{\sum_{i=1}^{100}x_i}{100}.

45 People are 65 and over

The number of people who are 65 and older is 45. There is no unbiased estimate for the average age of a population.

(b) Let's suppose we want to find y, such that \frac{y}{100} is an unbiased estimate for \frac{\sum_{i=1}^{100}x_i}{100}. Then \frac{y}{100} = \frac{\sum_{i=1}^{100}x_i}{100}. Let's now plug in 100 x −1 for \sum_{i=1}^{100}x_i. This means y = \frac{99 x − 1}{100}. (c) Recall that the average of a vector is 0 x + 1. Then the average age of the population is \frac{99 x −1}{100}. (d) An unbiased estimate for the average age of a population exists, because \frac{y}{100} ≠ \frac{\sum_{i=1}^{100}x_i}{100}.
