1.

  • Calculate the z score for each set of data. Determine who did better on her respective test, Tonya or Lisa.



Student English
Test Grade z-Score Student Math Test
Grade z-Score
John 82 Jim 81
Julie 88 Jordan 85
Samuel 90 Saye 79
Tonya 86 Lisa 82
Mean 86.50 81.75
St. Dev. 3.42 2.50

  • Given the above information, predict the raw score for a student whose z-score in the Math test is .98.


2.Draw a curve and shade the area between z = -1.15 and z = -1.35. Find the area associated with this section of the curve.
3.Draw a curve and shade the area between z = -.35 and z = .35. Find the area associated with this section of the curve.
4.Draw a curve and shade the area between z = 1.05 and z = 1.55. Find the area associated with this section of the curve.
5.Draw a curve and shade the area beyond z = 1.30. Find the area of the curve associated with this section of the curve.
