please anwser c
The acceptable level for insect fith in a certain food item is 2 insect fragments (larvae, eggs, body parts, and so on) per 10 grams. A simple random sample of 60 ton-gram portions x = 25 insect fragments per ten-gram portion Complete parts (a) through (e) below. (a) Why is the sampling distribution of x approximately normal? A The sampling distribution of x is assumed to be approximately normal O a The sampling distribution of x is approximately normal bicause the population is normally distributed and the sample size is large enough. OC. The sampling distribution of x is approximately normal because the population is normally distributed D. The sampling distribution of x is approximately normal because the sample size is large enough. (b) What is the mean and standard deviation of the sampling distribution of x assuming y = 2 and a = /22 H 2 (Round to three decimal places as needed.) 0 -0.183 Round to three decimal places as needed) (c) What is the probability a simple random sample of 60 ton gram portions of the food item results in a mean of at least 26 insect fragments? P225)-(Round to four decimal places as needed Step by Step Solution
