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 random sample of 50 ten-gram portions of the food item is obtained and results in a sample mean of x̅ =2.2 insect fragments per ten-gram portion. (a) What is the mean and standard deviation of the sampling distribution of x̅ assuming μ=2 and σ=√2 ? ******** I have multiple other parts after this...
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 60 ten-gram portions of the food item is obtained and results in a sample mean of x = 5.7 insect fragments per ten-gram portion Complete parts (a) through (c) below. (a) Why is the sampling distribution of x approximately normal? A. The sampling distribution of x is approximately normal because...

A government entity sets a Food Defect Action Level (FDAL) for the various foreign substances that inevitably end up in the foods we eat. The FDAL level for insect filth in peanut butter is 0.6 insect fragment (larvae, eggs, body parts, and so on) per gram. Suppose that a supply of peanut butter contains 0.6 insect fragment per gram. Compute the probability that the number of insect fragments in a 8-gram sample of peanut butter is (a) exactly six. Interpret...
The maximum acceptable level of a certain toxic chemical in vegetables has been set at 0.8 parts per million (ppm). A consumer health group measured the level of the chemical in a random sample of tomatoes obtained from one producer to determine whether the mean level of the chemical in these tomatoes exceeds the recommended limit. A. Two-tailed B. Left-tailed C. Right-tailed
Probe of level 8. (10 points) The maximum acceptable level of a certain toxic chemical in vegetables has been set at 0.4 parts per million (ppm).

section 9.4 Suppose the mean height of women age 20 years or older in a certain country is 62.5 inches. One hundred randomly selected women in a certain city had a mean height of 61.0 inches. At the 1% significance level, do the data provide sufficient evidence to conclude that the mean height of women in the city differs from the national mean? Assume that the population standard deviation of the heights of women in the city is 4.1 inches...
