-Sketch a normal distribution with (mu)
m =80 and standard deviation of (greek letter s) 20.

a)Locate each of the following scores in your sketch, and indicate whether you consider each score to be an extreme vaule(high or low) or a central value:

65,55,40,47

b)Make another sketch showing a distribution with mu=50, but this time with a standard deviation of 2. Now locate each four scores in the new distribution, and indicate whether they are extreme or central.
