A0.01 significance level is used for a hypothesis test of the claim that when parents use a particular method of gender? selection, the proportion of baby girls is less than 0.5.
assume that sample data consists of 66 girls in 144 births, so the sample statistic of startfraction 11 over 24 endfraction results in a z score that is 1 standard deviation below 0.
