The acceptable level for insect filth in a certain food item is 4 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 overbar equals =4.8 insect fragments per​ ten-gram portion

(Q1) What is the probability a simple random sample of 50 ten-gram portions of the food item results in a mean of at least 4.8 insect​ fragments?

The Food and Drug Administration establishes a Food Defect Action Level (FDAL) for the various foreign substances that inevitably end up in the food we eat and the liquids we drink. For example, the FDAL level for insect dirt in peanut butter is 0.1 insect fragments (larvae, eggs, body parts, etc.) per gram. Assume that a supply of peanut butter contains 0.1 insect fragments per gram. Calculate the probability that the number of insect fragments in a 10-gram peanut butter...
