(In some of the exercises that follow, we must make assumptions of normal distributions with the usual notation.)

In bowling, it is often possible to score well in the first game and then bowl poorly in the second game, or vice versa. The following six pairs of numbers give the scores of the first and second games bowled by the same person on six consecutive Tuesday evenings:

Assume a bivariate normal distribution, and use these scores to test the hypothesis H0: ρ = 0 against H1: ρ ≠ 0 at α = 0.10.

Psych Stats Powerpoint 6 ● we can identify important sections of the normal distribution using z- scores ● because we know what percent of scores falls in each part of the distribution, we can define the normal distribution in terms of proportions ○ these percentages/proportions apply to any normal distribution, regardless...
