Question

Normal probability Density Function Use a graphing utility to graph the model probability density function with ð = 1 and µ = 2,1, and 3

in the same viewing window.What effect does the mean µ have on the function?Explain your reasoning.

Answer 1

Explanation:

Hello!

The population mean (μ) is a measure of central tendency, this means, it shows you the position of the distribution. Changing the value of the mean changes the position of the bell over the axis but there is no change in its shape. The three normal distribution have the same standard deviation (δ), so they will have the same shape and only their positions vary.

Graph attached.

I hope it helps!
