Since we've determined that the Central Limit Theorem applies, let's calculate the probability: Assume that the standardized test scores of a certain group of high school students has an unknown distribution with a mean of 90 percent and a standard deviation of 15 percent. A sample size of n=31 is randomly drawn from a population. Use a calculator to find the probability that the sample mean is between 85 and 92 percent. If needed, round to the nearest hundredth. Provide your answer below:
$\mu_{\overline{x}}=$μx= %
$\sigma_{\overline{x}}=$σx= %
$P\left(85\le\overline{x}\le92\right)=$P(85≤x≤92)=

Applying the Central Limit Theorem:
The amount of contaminants that are allowed in food products is
determined by the FDA (Food and Drug Administration). Common
contaminants in cow milk include feces, blood, hormones, and
antibiotics. Suppose you work for the FDA and are told that the
current amount of somatic cells (common name "pus") in 1 cc of cow
milk is currently 750,000 (note: this is the actual allowed amount
in the US!). You are also told the standard deviation...

The population has mean μ=29 and standard deviation σ=9.
This distribution is shown with the black dotted line.
We are asked for the mean and standard deviation of the
sampling distribution for a sample of size 34. The Central Limit
Theorem states that the sample mean of a sample of size n is
normally distributed with mean μx¯=μ and σx¯=σn√.
In our case, we have μ=29, σ=9, and n=34. So,
μx¯=29
and
σx¯=934‾‾‾√=1.5
This distribution is shown with the red...

Use the central limit theorem to find the mean and standard
error of the mean of the indicated sampling distribution. Then
sketch a graph of the sampling distribution. The per capita
consumption of red meat by people in a country in a recent year was
normally distributed, with a mean of 111 pounds and a standard
deviation of 38.7 pounds. Random samples of size 17 are drawn from
this population and the mean of each sample is determined. mu
