A random sample of 30 varieties of cereal was selected. The average number of calories per serving for these cereals is *x*̄ = 120. Assuming that *σ* = 10, find a 95% confidence interval for the mean number of calories, *μ*, in a serving of cereal.

Step 1

From the provided information,

Sample size (*n*) = 30

Average number of calories (*x̄*) = 120

And *σ* = 10

The critica...
