a)
To read: The two digit number for days in column 5.
Introduction: The amount of the dependency on human effort by an organization, in terms of achieving its goals is given by the work design. It is directly linked to the productivity of an organization, where a good work design helps in achieving high productivity.
b)
To determine: The hours from row 1, using its first digit.
Introduction: The amount of the dependency on human effort by an organization, in terms of achieving its goals is given by the work design. It is directly linked to the productivity of an organization, where a good work design helps in achieving high productivity.
c)
To determine: The minutes reading in the last two digits going down in column 6 and then repeating them, taking the first two digits and then making a chronological arrangement of days, hours and minutes.

- Your twenty observations of Dr. Knowitall reveal the following information. Assume that the estimate is to be within 5 percent of the true proportion 96 percent of the time Activity Observed Number of Times Observed With patient 6 Reviewing test results 5 On phone 5 Idle 3 Away on emergency 1 Not available 1 Total 21 Calculate the sample size needed to estimate the proportion of time Dr. Knowitall spends away on emergencies.arrow_forwardHow reliable is the result of work sampling activity in determining working time and idle time of the operator?arrow_forwardPrepare a run diagram for this emergency call data. Use five-minute intervals (i.e., count the calls received in each five- minute interval. Use intervals of 0-4, 5-9, etc.). Note: Two or more calls may occur in the same minute; there were three operators on duty this night. What can you conclude from the run chart?

Provide your diagram that shows the number of emergency calls by eacn five-minute intervals from 1am to 2:20am c. what can you conclude from the chart?arrow_forward
- An analyst has been asked to prepare an estimate of the proportion of time that a turret lathe operator spends adjusting the machine, with 90% confidence level. Based on previous experience, the analyst believes the proportion will be approximately 30%. a. If the analyst uses sample size of 400 observations, what is the maximum error that will be associated with the estimate? b. What sample size would the analyst need in order to have the maximum error be no more than +/- 5%?arrow_forward24.

- Compare stopwatch time study and work sampling.arrow_forwardAn analyst made 30 observations over 15 minutes during which 12 units where produced. For 9 observations, the worker was seen working. Compute for the observed time.arrow_forwardK 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 0.08arrow_forward
- What would typically happen if an abnormally short time was recorded when conducting a stopwatch time study? a) It would be included in the study. b) It would be discarded. c) It would be factored by the performance rating. d) Inform the supervisor of the abnormality.arrow_forward4. In a restaurant, a customer was asked about his level of satisfaction about their service.
