A company checking the productivity of its assembly line monitored a random sample of workers for several days. They found that a 95% confidence interval for the mean number of items produced daily by each worker was (23,27). Which of the following is a correct interpretation of the confidence interval? Either the mean daily worker output is between 23 and 27 items, or else our sample is among the 5% most unusual that could have been obtained.95% of all the workers average between 23 and 27 items a day. 95% of the workers sampled produced between 23 and 37 items a day.Workers produce an average of 23 to 27 items on 95% of the days.95% of samples would show mean production between 23 and 27 items a day.
