Document Summary

To find the pth value: 0 < p < 1. On calc: 2nd, dist, inverse norm, enter, (p, , ) You can check by using normalcdf, (-10^99, inverse norm function, , ), should come out to the given area (p) If p < 0. 5, b is to the left of the mean. If p > 0. 5, b is to the right of the mean. P includes the area to the left. If finding the area to the right using the percentiles. Or plug in each multiple choice question into normal cdf. Area to the left and right of the mean is always 0. 5. To find points for equal distance area: find area outside, use inverse norm, add the difference to the mean. Alpha is the area to the right of the point. On calc: zalpha = inverse norm (1-alpha) The area to the left is 1- alpha. The sliver to the left is -zalpha.
