The acceptable level for insect filth in a certain food item is 2 insect fragments (larvae, eggs, body parts, and so on) per 10 grams. A simple randomsample of 60 ten-gram portions of the food item is obtained and results in a sample mean of x = 2.6 insect fragments per ten-gram portion. Completeparts (a) through (c) below.Click here to view the standard normal distribution table (page 1).Click here to view the standard normal distribution table (page 2).(a) Why is the sampling distribution of x approximately normal?O A. The sampling distribution is approximately normal because the sample size is large enough.B. The sampling distribution is approximately normal because the population is normally distributed and the sample size is large enough.OC.

Since this result is not unusual, it is reasonable to conclude that the population mean is higher than 2.OC. Since this result is not unusual, it is not reasonable to conclude that the population mean is higher than 2.OD. Since this result is unusual, it is reasonable to conclude that the population mean is higher than 2.
