Answer #1

Solution:

Given:

Mean =

Standard Deviation =

We have to convert given raw scores ( that is x values) to z score.

Part A) What is Z score if X is 115?

We use following z score formula:

Put x = 115 in z score formula:

Part B) What is the Z score if X is 121?

Put x = 121 in z score formula:

In a study on the physical activity of people, researchers measured overall physical activity as the total number of registered movements (counts) over a period of time and then computed the number of counts per minute (cpm) for each subject. The study revealed that the overall physical activity of obese people has a mean of μ=322cpm and a standard deviation σ=92cpm. In a random sample of 100 obese people, consider x ̅, the sample mean counts per minute. 3) What...

In each problem, make sure that you are clearly defining random variables, stating their distributions, and writing down the formulas that you are using. (That is, write down the pmf, write down mean and variance formulas.) One of the most common places where normal distributions naturally arise is from the distribution of measurement error. A good example of this would be the old fashioned resistors which are used in electrical circuits. Factories can’t produce perfectly accurate products, so these resistors...
