| Feb 14, 2014 at 3:11 | comment | added | gung - Reinstate Monica | This is a possible, but poor, strategy. It is recommended that you use Levene's test or the Brown-Forsythe test for this (see my answer here). | |

What kind of test should I use if H_0: p = alpha against H_1: p ≠ alpha ? How do you contain the number of successes in the R code?
