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 78 girls in 169 births, so the sample statistic of 13 results in a z score that is 1 standard deviation below 0. Complete parts (a) through (h) below. lick here to view pag e Normal table. Click here to view page...
