A 0.01 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 different from 0.5. Assume that sample data consists of 55 girls in 100 births, so the sample statistic of 11 20 results in a z score that is 1 standard deviation above 0. Complete parts (a) through (h) below.
