Question

must be done on minitab 18

QUESTION 3 The location of a Normal distribution is determined by its mean u, where as its shape is determined by the standard deviation ơ. To see the effect of changing , you are going to graph two Normal probability density functions, one with u 100 and another with u 105, both having σ = 10, Recall that for each distribution the first value should be 3σ = 30 below the mean, and the last value should be 3ơ above the mean. When MINITAB creates the X values for you, for both distributions set the data IN STEPS OF 1. Overlay the two density functions on the same graph (in MINITAB), and paste in the box below.
