Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean u = 207 and standard deviation = 17 days.
(a) What is the probability that a randomly selected pregnancy lasts less than 201 days?
(b) What is the probability that a random sample of 16 pregnancies has a mean gestation period of 201 days or less?
(c) What is the probability that a random sample of 37 pregnancies has a mean gestation period of 201 days or less?

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
