Question

Use Minitab to solve and illustrate the following problems. X has a Chi-square distribution with 14 degrees of freedom.

1. P(X < 10)

2. P(X > 16)

3. P(8 < X < 17)

4. Find x so that P(X < x) = .25

5. Find x so that P(X > x) = .15

6. Find constants a and b so that P(X<a) = .1 and P(a<X<b) = .8.

Minitab will produce a graph which illustrates and answers problem 1. Right click on the graph and select send graph to Microsoft Word. Keep word document minimized while you finish the other five graphs.
