Question

does anyone know anything about minitab and z scores I can post the question

Answer 1

Using the database convert each subject's age and height into a z-score.
Using the z-score of ±1.645 for the 5 percent cutoff and the z-score of ±1.96 for the 2.5 percent in the tail, identify the subject identification (ID) number for subjects who are closest to the cutoff for the upper 2.5 percent and 5 percent of the scores and the lower 2.5 percent and 5 percent of the scores.
Save the Minitab worksheet.
