After​ training, Mary​ Fernandez, a computer​ technician, had an average observed time for​ memory-chip tests of 12 seconds.​ Mary's performance rating is 100​%. The firm has a personal fatigue and delay allowance of 18​%. Part 2 ​a) The normal time for this process​ = enter your response here   seconds ​(round your response to two decimal​ places). Part 3 ​b) The standard time for this process​ = enter your response here   seconds ​(round your response to two decimal​ places).

Supervisor Kenneth Peterson wants to determine the percent of time a machine in his area is idle. He decides to use work​ sampling, and his initial estimate is that the machine is idle 18​% of the time. ​(Round all intermediate calculations to at least two decimal places before proceeding with further​ calculations.) Part 2 The number of observations that need to be taken by Peterson to be 98.00​% confident that the results will be less than 6​% from the true result​ = enter your response here   ​(round your response to the immediate higher whole​ number).

The “worker” in this scenario had to perform a candy-sorting task and the rest of the class had to record the observed times (OT) for the task. It was decided that the rating for the “worker” was 100%. Given the following table, find the standard time for each element. Write your answers in order from Element #1 --> Element  #5. Answers must have one decimal place: e.g. 3.0 or 12.5. Round up if necessary.  Assume a total allowance of 5%. In your equation you will use for ST, consider allowance to be 0.05.    Element Trail 1 Trial 2 Standard Time 1 Walk to podium 3 sec 3 sec   2 Fill mug 5 sec 6 sec   3 Walk to desk/sit 5 sec 4 sec   4 Sort Candy 12 sec 12 sec   5 Walk to desk 4 sec 4 sec

After training, Mary Fernandez, a computer technician, had an average observed time for memory-chip tests of 12 seconds. Mary's performance rating is 95%. The firm has a personal fatigue and delay allowance of 12%. a) The normal time for this process = seconds (round your response to two decimal places). b) The standard time for this process = seconds (round your response to two decimal places).

Estimate the number of repetitions that new service worker Irene will require to achieve “standard” if the standard is 18 minutes per repetition. She took 30 minutes to do the initial repetition and 25 minutes to do the next repetition.

After​ training, Mary​ Fernandez, a computer​ technician, had an average observed time for​ memory-chip tests of 15 seconds.​ Mary's performance rating is 105​%. The firm has a personal fatigue and delay allowance of 12​%. ​a) The normal time for this process​ = seconds ​(round your response to two decimal​ places). ​b) The standard time for this process​ =seconds ​(round your response to two decimal​ places).

From a time study, the worker’s average observed time for a particular task is shown to be 5.6 minutes.  The analyst feels the worker was performing their task, on average, about 25% faster than normal.  What would be the resulting standard time assuming a 20% allowance for fatigue and personal needs?

K Claudine Soosay recorded the following times assembling a watch: Observation No. 1234567co 8 Time (minutes) 0.12 0.10 0.11 0.11 0.15 0.10 0.10 0.10 Observation No. 9 10 11 12 13 14 15 16 Time (minutes) 0.11 0.08 0.11 0.10 0.10 0.11 0.14 0.08

Eight instances of a worker doing a task were observed as follows:  How many observations would be needed to be 99.74 percent confident that the maximum error is 5 percent of the observed time? Assume that the standard deviation of the task time is two seconds.
