You have performed a work sampling study in a job shop and have made a total of 50 observations. During the observations, you have noticed that a worker is taking a break 2 times, chatting to a co-worker 2 times, and is absent from the workstation once. Based on these observations, you are 95% confident that the worker has only worked between 81.7% and 98.3% of the time. However, in the final report you claim that you are 95% confident that the worker has worked between 87% and 93% of the time. What changes did you make in the study to reflect your claim in the final report
