Web1. There is an annoying possibility of confusion in notations such as Z 0.05, which usually means a z-value that cuts 5% of the probability from the upper tail of the dist'n; that's +1.645. By contrast 'quantile 0.05' cuts 5% prob from the lower tail; that's -1.645. // Software tends to use the 'quantile' notation; printed tables tend to use ... interactive 3d globeWebNow use the function NORMSINV(p) to calculate the z score that corresponds to this alpha. Your p is the bottom portion and you should get a z = 1.645, you will see this value many times in the next few weeks.

For Ha: p ≠ 26, the P-value would be P (z ≤ -1.83) + P (z ≥ 1.83) = 2 * P (z ≤ -1.83). Regardless of Ha, z = (p̂ - p0) / sqrt (p0 * (1 - p0) / n), where z gives the number of standard deviations p̂ is from p0.
