the lengths of the pregnancies of a certain animal are approximately normally distributed with mean p = 212 days and standard deviation a = 20 days. Complete parts (a) through (f) below. it is the probability that a randomly selected pregnancy lasts less than 206 days? bability that a randomly selected pregnancy lasts less than 206 days is approximately (Round to four decimal places as needed.) t this probability. Select the correct choice below and fill in the answer box within your choice. to the nearest integer as needed.) f 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last exactly 206 days. I 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last more than 206 days. f 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last less than 206 days. pose a random sample of 21 pregnancies is obtained. Describe the sampling distribution of the sample mean length of pregnancies. mpling distribution of x is With ; = and o= = to four decimal places as needed.) t is the probability that a random sample of 21 pregnancies has a mean gestation period of 206 days or less? bability that the mean of a random sample of 21 pregnancies is less than 206 days is approximately to four decimal places as needed.) t this probability. Select the correct choice below and fill in the answer box within your choice, to the nearest integer as needed.) f 100 independent random samples of size n = 21 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 206 if 100 independent random samples of size n = 21 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 206 days o f 100 independent random samples of size n = 21 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 206 days of I is the probability that a random sample of 46 pregnancies has a mean gestation period of 206 days or less? bability that the mean of a random sample of 46 pregnancies is less than 206 days is approximately to four decimal places as needed.) t this probability. Select the correct choice below and fill in the answer box within your choice, to the nearest integer as needed.) I 100 independent random samples of size n = 46 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 206 days c If 100 independent random samples of size n = 46 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 206 days o 100 independent random samples of size n = 46 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 206 I might you conclude if a random sample of 46 pregnancies resulted in a mean gestation period of 206 days or less? ult would be so the sample likely came from a population whose mean gestation period is Y 212 days. is the probability a random sample of size 20 will have a mean gestation period within 9 days of the mean
