Part1:

1. Given the raw data in Table I. Make a frequencyr table and using the fre quency tahle, solve for the mean of the data. Table l 2.. Find the range of 34,45, 16,6143, 56,99,23,45 and T6. 3. A consumer group tested a sample of 8 sizedD batteries from each of 3 companies. The results of the tests are shown in the following table. According to these test, which companyI produces batteries for which the values representing hours of constant use have the smallest standard deviation? Among the data given, which company has the most spread out data set? Hours ofcolltant use per battery EverSoBright 6.2, 6.4, 3.1, 5.9, 8.3, 5.3, '15, 9.3 6.8, 6.2, 12, 5.9, 7.8, 14, '13, 8.2 6.1, 6.6, 13,53", 11,16, '1], 8.5 BUNDLE QUESTIIDN (5 pts) If the average of two datas is 5 and their range is 6.
