1) Evaluate the attached time study sheet. All data in the W column are times that have been gathered using a continuous stopwatch method. All times are in minutes, tenths of minutes and hundredths of minutes. Please answer on the time study sheet where possible. a) What are the normal times for each element? b) What are the standard times for each element? c) What is the standard time for one cycle of this job? d) Based on the data for Element 2 how many work cycles are needed if you would like at least 95% confidence that your estimated value is within +/- 6% of the true value of the normal time for this element.
