0.1 significance level is used for a hypothesis test of the claim that when parents use a particular method of genderselection, the proportion of baby girls is less

less than 0.5. Assume that sample data consists of 66

66 girls in 144

144 births, so the sample statistic of StartFraction 11 Over 24 EndFraction

1124 results in a z score that is 1 standard deviation below

below 0. Complete parts(a) through(h) below.
