(Round to the nearest integer as needed.) O A. If 100 independent random samples of size n = 55 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of 228 days or more B. If 100 independent random samples of size n = 55 pregnancies were obtained from this population, we would expect |0 sample(s) to have a sample mean of 228 days or less. O C. If 100 independent random samples of size n = 55 pregnancies were obtained from this population, we would expect sample(s) to have a sample mean of exactly 228 days. (e) What might you conclude if a random sample of 55 pregnancies resulted in a mean gestation period of 228 days or less? This result would be | unusual, so the sample likely came from a population whose mean gestation period is less than 233 days, (f) What is the probability a random sample of size 19 will have a mean gestation period within 11 days of the mean? The probability that a random sample of size 19 will have a mean gestation period within 11 days of the mean is (Round to four decimal places as needed )
