Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean

μ=293 days

and standard deviation

σ=21 days.

Complete parts (a) through (f) below.

d) What is the probability that a random sample of

pregnancies has a mean gestation period of

285

days or less?

The probability that the mean of a random sample of

pregnancies is less than

285

days is approximately

nothing.

(Round to four decimal places as needed.)
