Chapter 6: Normal Probability Distributions
... 1. Sketch a normal curve, label the mean and the specific x values, then shade the region representing the desired probability 2. For each relevant value x that is a boundary for the shaded region, use the formula to convert that value to the equivalent z score 3. Use Table A-2 or a graphing calcula ...

... 62. If the original data is not normal, what happens to the shape of all sample means from samples of size n as n goes up? What is the name of this theorem? 63. Consider data sets A:{25,26,26,25,24} and B:{15,25,38,22,40}. If you know one set of data is 5 individuals and the other is 5 averages, wh ...

... A large value of F indicates relatively more difference between groups than within groups (evidence against H0) To get the P-value, we compare to F(I-1,n-I)-distribution • I-1 degrees of freedom in numerator (# groups -1) • n - I degrees of freedom in denominator (rest of df) ...
