Please answer:

1. A simple random sample of size n=53 is obtained from a population with ?=64 and ?=7. Does the population need to be normally distributed for the sampling distribution of x to be approximately normally?distributed? Why? What is the sampling distribution of x??
2. A simple random sample of size n=43 is obtained from a population with ?=81 and ?=4. Does the population need to be normally distributed for the sampling distribution of x to be approximately normally?distributed? Why? What is the sampling distribution of x??

What is the sampling distribution of it\"? Select the correct choice below and ll in the answer boxes Iwithin your choice. {Type integers or decimals rounded to three decimal places as needed} 0 A- The sampling distribution of i: is normal or approximately normal with \"I: = D and e; = D. C} E- The sampling distribution of it follows Student's tdistribution with p; = D and e; = D. Q C- The sampling distribution of x is skewed left with \"5: = D and \"it = D. C} D- The sampling distribution of x is uniform with "i = D and \"i = D
