The error was made by the cable company's specifications provided to the overseas supplier. The operations manager calculates that it would be cheaper to manually change the connectors rather than the supplier re-doing or fixing the cables. The manager observes the first set of workers pulled aside to change the cables and | from these observations will set a standard time. The observations are as follows for workers to each change the connectors on sets of 20 cables. Time The manager will use a performance rating Observation [min) factor of .95 and an allowance factor of .04. 7.17 7.23 36'9 7.05 ONGUAWN 7.54 7.33 5 7.11 7.27 7.09 10 6.99 Page 5 of 10 2359 words English (United States) Text Predictions: On ?

Save Determine the standard time the manager will use to change the connectors. Average Observation Time = (7.17 + 7.23 + 6.98 + 7.05 + 7.54 + 7.33 + 7.11 + 7.27 + 7.09 + 6.99) / 10 Average Observed Time = 7.1760 minutes Normal cycle time = Average observation time*Performance rating factor Normal cycle time = 7.176*0.95 Normal cycle time = 6.8172 minutes Standard time = Normal time / (1 - allowance factor) Standard time = 6.8172/(1-0.04) Standard time = 7.1013 minutes Therefore, The standard time the manager will use to change the connectors is 7.1013 minutes 7. Sample size ( 10 marks) The operations manager from Q6 wants to make sure the right sample size was used to collect the observations and calculate the standard time. The company's owner will be satisfied within an accuracy 2% in the time estimates but wants to be 99% confident. Determine if the sample size of 10 that was used was sufficient to meet the owner's expectations. Describe your findings. Hint: You will have to recall how to calculate the standard deviation from the observations in Q6. Page 6 of 10 2359 words English (United States) Text Predictions: On ?
