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 50 ten-gram portions of the food item is obtained and results in a sample mean of x- 5.3 insect fragments per ten-gram portion. Complete parts (a) through (c) below. (a) Why is the sampling distribution of x approximately normal? O A. The sampling distribution of x is approximately normal because the sample size is large enough. O B. The sampling distribution of x is approximately normal because the population is normaly distributed. OC. 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.
