Question
7.1-6. To determine whether the bacteria count was lower
in the west basin of Lake Macatawa than in the east
basin, n = 37 samples of water were taken from the
west basin and the number of bacteria colonies in 100
milliliters of water was counted. The sample characteris-
tics were = 11.95 and s= 11.80, measured in hundreds
of colonies. Find an approximate 95% confidence interval
for the mean number of colonies (say, w) in 100 milliliters
of water in the west basin.
