The acceptable level for insect filth in a certain food item is 5 insect fragments (larvae, eggs, body parts, and so on) per 10 grams. A simple random sample of 6 ten-gram portions of the food item is obtained and results in a sample mean of x = 5.8 insect fragments per ten-gram portion Complete parts (a) through cj below (a) Why is the sampling distribution of x approximately normal? O A. The sampling distribution of x is approximately normal because the population is normally distributed. B. The sampling distribution of x is approximately normal because the sample size is large enough. O C. The sampling distribution of x is assumed to be approximately normal. OD. The sampling distribution of x 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 u=5 and o =5?
