The density of cheese produced in a factory is approximately normally distributed with a mean of 1.8 g/cm3 and standard deviation of 0.3 g/cm3.What is the probability of obtaining a sample standard deviation greater than 0.5 g/cm3 for a sample of size 8? (chi2cdf(19.444,7)=0.9931)
Added by Mitchell S.
Step 1
8 g/cm³ and standard deviation (σ) = 0.3 g/cm³. We need to find the probability of obtaining a sample standard deviation (s) greater than 0.5 g/cm³ for a sample of size (n) = 8. Show more…

The distribution of actual weights of 8-ounce wedges of cheddar cheese produced at a dairy is Normal, with mean 8.05 ounces and standard deviation 0.3 ounces. A sample of 9 of these cheese wedges is selected: What is the standard deviation of the sampling distribution of the sample mean? 2.68 ounces 0.1 ounces 0.033 ounces 0.3 ounces

The distribution of actual weights of wedges of cheddar cheese produced at a dairy is normal with a mean of 11.3 ounces and a standard deviation of 0.19 ounces. (Round to 2 decimal places for all z-values and round all other answers to 4 decimal places, if needed.) The probability that the sample mean weight of this sample of 20 is less than 11.23 is .

The distribution of actual weights of wedges of cheddar cheese produced at a dairy is normal with a mean of 11.9 ounces and a standard deviation of 0.19 ounces. (Round all answers to 4 decimal places, if needed) e) The probability that the sample mean weight of this sample of 19 between 11.87 and 11.96 is f) There is only a 2% chance that the average weight of a sample of these 19 cheese wedges will be below
