Can I get help with C?

image text in transcribed
The length of human pregnancies is approximately normalwith mean p = 266 days and standard deviation 0' = 15 days. Complete parts (a) through (f). E) (a) What is the probability that a randomly selected pregnancy lasts less than 262 days? The probabity that a randomly selected pregnancy lasts less than 262 days is approximately 0.4013, (Round to tour decimal places as needed.) 3 Interpret this probability. Select the correct choice below and ll in the answer box within your choice. (Round to the nearest integer as needed.) , O A- It 100 pregnant individuals were selected independently from this population, we would expect pregnancies to last exactly 262 days. C? B- It 100 pregnant individuals were selected independently from this population. we would expect 40 pregnancies to last less than 262 days. 0 c- If 100 pregnant individuals were selected independently from this population, we would expect ' i. pregnancies to last more than 262 days. (b) Suppose a random sample of 63 human pregnancies is obtained. Describe the sampling distribution of the sample mean length of pregnancies. I} m. The sampling distribution or i is normal with p; = 266 and a; = 2.0158. (Type integers or decimals rounded to tour decimal places as needed.) (c) What is the probability that a random sample of B3 pregnancies has a mean gestation period of 262 days or less? The probability that the mean of a random sample of 53 pregnancies is less than 262 days is approximately D. (Round to four decimal places as needed.)
