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 μ = 3.66 and standard deviation σ = 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 60 % of all random samples of such squirrels of size n = 30 , the mean number of pups born to females in the sample is less than ¯¯¯ x .
