My 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 greater than 0.5. Assume that sample data consists of 66 girls in 121 births, so the Co 6 sample statistic of 7 results in a z score that is 1 standard deviation above 0. Complete parts (a) through (h) below.
