In a population of Siberian flying squirrels in western Finland, assume that the the number of pups born to each female over her
lifetime has mean = 3.66 and standard deviation 2.9598. The distribution of squirrel pups born is non-normal because it
takes only whole, non-negative values.
Determine the mean number of pups, x, such that in 70% of all random samples of such squirrels of size n = 40, the mean
number of pups born to females in the sample is less than X.
You may need to use software or a table of z-critical values. You may find some software manuals useful.
Give your answer to at least two decimal places.
