  1. Chapter 7Minitab Recipe Cards

  2. Select Probability Distributions from the Calc menu and Normal from the sub-menu. The normal distribution

  3. For the cumulative probability for Example 7.1 select Cumulative probability in the command window. Specify the Mean (18) and Standard deviation (3). Choose Input constant and type 13 in the adjacent space. Click OK.

  4. The probability appears in the session window.

  5. Select Probability Distributions from the Calc menu and t from the sub-menu. The t distribution

  6. For P (t > 0.25) in Example 7.11 select Cumulative probability in the command window and specify 8 Degrees of freedom (the sample size less one). Choose Input constant and type 0.25 in the adjacent space. Click OK.

  7. The probability that t is less than 0.25 appears in the session window. Subtract this from 1 to give P (t > 0.25).
