32. A study was conducted on the lengths of the logs from each lot

(in Q 31). Samples were taken and the observations were as follows:

Lot 1 (in feet): 102, 86, 98, 109, 92

Lot 2 (in feet): 81, 165, 97, 134, 92, 87, 114

a)Is the mean log length of Lot 2 significantly different from 100 feet? (use a hypothesis test at= 0.05)

b)Is there a significant difference in log length between the two lots? (use a hypothesis test at= 0.05 and assume that12 22
