Test at a 1% level of significance. a) If we use B to denote the boys and G to denote the girls, identify the correct alternative hypothesis. O H1:PB < pg="" h1:pb=""> PG H1:PB + PG b) Determine the test statistic. Round to two decimals. z = c) Find the p-value and round to 4 decimals. d) Make a decision.
