Please help me with Question (b).

1.Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean mu equals 214 days

μ=214 days and standard deviation sigma equals 19 days

σ=19 days. Complete parts (a) through (f) below.

**(a)** What is the probability that a randomly selected pregnancy lasts less than 208 days?

2.The probability that a randomly selected pregnancy lasts less than 208 days is approximately .3761. (Round to four decimal places as needed.)

Interpret this probability. Select the correct choice below and fill in the answer box within your choice.

(Round to the nearest integer as needed.)

If 100 pregnant individuals were selected independently from this population, we would expect

38 pregnancies to last less than 208 days.

Your answer is correct.

**(b)** Suppose a random sample of 22 pregnancies is obtained. Describe the sampling distribution of the sample mean length of pregnancies.

The sampling distribution of x is ______

with mu Subscript x = _______

and sigma Subscript x = _______
