Document Summary

Look up 1. 5 in the margins on the table = 0. 4332. 93. 32% of the data falls below a point that lies 1. 5 standard deviations above the mean. 6. 68% of the data falls below a point that lies 1. 5 sd below the mean. 71. 34% of data falls b/w a point that is 1. 7 sd below the mean and a point that is 1. 7. 0. 4918 - 0. 4452 = 0. 0466 = 4. 6% of the data falls b/w these two points. Add the information to the z-score formula and isolate for x. 12(1. 7) + 74 = x, therefore x = 94. 4. Enter the data into the t-score formula and isolate for z. Enter the data into the z-score formula and isolate for x. Look in the body of the z-table for 0. 22 (z=0. 58) is the closest value. T = 10 (0. 58) + 50 = 55. 8.
