A 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 different from 0.5.
Assume that sample data consists of 55 girls in 100 births, so the
sample statistic of 11/20 (Fraction)
results in a z score that is 1 standard deviation above 0. Complete
parts (a) through (h) below.
A. Identify the Null hypothesis and alternative
B. What is the value of alpha?
C. What is the sampling distribution?
Normal Distribution, Student (t) distribution, or x^2
D. Is the test two tailed, left tailed or right tailed?
E. What is the value of the test statistic?
F. What is the P-Value?
G. What are the critical values? (round to three decimal places)
H. What is the area of the critical region? Round to two decimal places
