According to a study, the length of pregnancy of a randomly selected female has an unknown distribution with a mean of 271 days and a standard deviation of 14.8 days. Let X be the length of pregnancy for a randomly selected female and let X be the average length of pregnancy for a random sample of size 36. 1. Describe the probability distribution of X and state its parameters and o: X~ unknown (H=271 ✓o 14.8✔ and find the probability that the length of pregnancy for a randomly selected female is between 246 and 286 days. 0.7983 x (Round the answer to 4 decimal places) 2. Use the Central Limit Theorem the sample size is large (n>30) although the distribution of the original population is unknown to describe the probability distribution of X and state its parameters μx and ox: (Round the answers to 1 decimal place) (FX 2710x2.5 ✓ and find the probability that the average length of pregnancy for a sample of 36 randomly selected females is more than 278 days. X ~N 0.0026✓ (Round the answer to 4 decimal places)
