Hey there! Thank you for posting the question. Since your question has more than 3 parts, we are…

ie lengris the pregnancies of a certain animal are approximately normally distributed with mean p= 170 days and standard deviation o = 15 days.

(a) What is the probability that a randomly selected pregnancy lasts less than 164 days? The probability that a randomly selected pregnancy lasts less than 164 days is approximately (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.) O A. If 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last less than 164 days. O B. If 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last exactly 164 days. O C. If 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last more than 164 days. (b) Suppose a random sample of 17 pregnancies is obtained. Describe the sampling distribution of the sample mean length of pregnancies. The sampling distribution of x is (Round to four decimal places as needed.) normal with ; = 170 and o: = 3.638 (c) What is the probability that a random sample of 17 pregnancies has a mean gestation period of 164 days or less? The probability that the mean of a random sample of 17 pregnancies is less than 164 days is approximately (Round to four decimal places as needed.)
