0.05 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 78 girls in 169 births, so the sample statistic of 6 13 results in a z score that is 1 standard deviation below 0. Complete parts (a) through (h) below.
