A simple random sample of 44 female cotton mouths yielded the following data on number of young per litter.
5 12 7 7 6 8 12 9 7
4 9 6 12 7 5 6 10 3
10 8 8 12 5 6 10 11 3
8 4 5 7 6 11 7 6 8
8 14 8 7 11 7 5 4
a. Use the data to obtain a point estimate for the mean number of young per litter, µ, of all female eastern cottonmouths. (Note: ?x_1 = 334.)
b. Is your point estimate in part (a) likely to equal µ exactly? Explain your answer.
