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

Suppose the lengths of the pregnancies of a certain animal are approximately normally distributed with mean p= 170 days and standard deviation o= 15 days. Complete parts (a) thu Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). (d) What is the probability that a random sample of 34 pregnancies has a mean gestation period of 164 days or less? The probability that the mean of a random sample of 34 pregnancies is 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.) sample(s) to have a sample mean of 164 days or less. O A. If 100 independent random samples of size n= 34 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 164 days or more. O B. If 100 independent random samples of size n= 34 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 164 days. O C. If 100 independent random samples of size n= 34 pregnancies were obtained from this population, we would expect (e) What might you conclude if a random sample of 34 pregnancies resulted in a mean gestation period of 164 days or less? 170 days. This result would be V so the sample likely came from a population whose mean gestation period is (f) What is the probability a random sample of size 20 will have a mean gestation period within 10 days of the mean? (Round to four decimal places as needed.) The probability that a random sample of size 20 will have a mean gestation period within 10 days of the mean is (1,1)
