WebThe equation ϕ = π / 2 corresponds to the x y -plane. The surface ϕ = constant is rotationally symmetric around the z -axis. Therefore it must depend on x and y only via the distance x 2 + y 2 from the z -axis. Using the relationship (1) between spherical and Cartesian coordinates, one can calculate that Webthe one-tailed probability would be the sum of the separate probabilities for the arrays And the two-tailed probability would be that sum plus the sum of the separate probabilities for the arrays of equal or greater disproportion at the other extreme: two-tailed probability = 0.01852 + 0.00449 = 0.02301 Return to Top ©Richard Lowry 1998- 2024
