The acceptable level for insect fith i certain food tem is 5 insect fragments (arvae, eggs, body parts, and so on) per 10 grams. A simple random sample of 50 ten-gram portions of the food them is obtained and results in a sample mean 5.7 insect fragments per ten-gram portion Complete parts (a) through (c) below Click here to view the standa distribution table (page 11 Click here to view the standard normal distribution table 21 (a) Why is the sampling distribution of x approximately normal? A The sampling distribution is approximately normal because the sample size is large enough OB The sampling distribution is approximately normal because the popluation is normally distributed OC. The sampling distribution is assumed to be approximately normal OD. The sampling distribution is approximately normal because the population is normally distributed and the sample size is large enough (b) What is the mean and standard deviation of the sampling distribution of x assuming-5 and 57 Round to three decimal places as needed)

Pls help both A to D and A to C
The acceptable level for insect fith in a certain food item is 5 insect fragments (arvae, eggs, body parts, and so on) per 10 grams. A simple random sample of 50 en-gram portions of the food item is obtained and results in a sample mean of x-5.7 insect fragments per ten-gram portion Complete parts (a) through (c) below Click here to view the landard normal distribution table in 11 standand normal distribution table (page 21 (a) Why is the sampling distribution of approximately normal? A. The sampling distribution is approximately normal because the sample size is large enough OB. The sampling distribution is approximately normal because the popluation is normally distributed C. The sampling distribution is assumed to be approximately normal OD. The sampling distribution is approximately normal because the population is normally distributed and the sample size is large enough (b) What is the mean and standard deviation of the sampling distribution of x assuming Sande-57 (Round to three decimal places as needed)
