With reference to the previous exercise, construct a 98% confidence interval for the true population mean number of unremovable defects per display.

Data From Previous Exercise

7.5 The manufacture of large liquid crystal displays (LCD's) is difficult. Some defects are minor and can be removed; others are unremovable. The number of unremovable defects, for each of n = 45 displays (Courtesy of Shiyu Zhou) 900 150 5 3 0 7 6 9 1 0 8 6 0 10 0 6 0 0 1 5 1 0 5 0 02 420 0312 0000 6 0 0 800 has 2.467 and s = 3.057 unremovable defects. What can one assert with 98% confidence about the maximum error if x = 2.467 is used as a point esti- mate of the true population mean number of unremov- able defects?
