A 0.01 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 greater than 0.5. Assume that sample data consists of 91 girls in 169 births, so the sample statistic of seven thirteenths results in a z score that is 1 standard deviation above 0. Complete parts (a) through (h) below
. a. Identify the null hypothesis and the alternative hypothesis.
b. what is the value of a?
c. What is the sampling distribution of the sample statistic?
---X^2
---Student (t) distribution
--- Normal Distribution
d. Is the test two-tailed, left-tailed, or righ tailed?
e. what is the value of the test statistic? f. what is the P-value?
g. what are the critical Value(s)?
h. What is the area of the critical region?
