The normal distribution is a “continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of the left side.” (Mcleod, 2019) The area under the normal distribution curve represents probability and the total area under the curve sums to one. (Mcleod, 2019)…
On a spreadsheet should have 20 “height” values listed below, along with my height of 64 inches as the “x” value. And then remember, you’re going to find the mean and the sample standard deviation. Give us a background. People that you chose maybe come up with an Excel spreadsheet. Where do you have? You…

Regression analysis can estimate the magnitude of the impact of a change in one variable or another (Holmes et al., 2017). If regression analysis were to be completed on BMI, an independent variable associated with that would be height and weight. The size and weight are how the BMI is calculated. Usually, as we get…
With pain being the 6th vital sign, working in intake it is important to ask about our patients’ current pain. For 12 intake inmates reporting pain on a numerical scale of 1- 10, the mean pain rating is greater than 5/10. The variable is the pain rating for the incoming patients. I predicted that the…
