Question
A 0.01 significance level is used for a hypothesis test of claim that when parents use a particular method of gender selection, the proportion of baby girls is less than 0.5. Assume that sample data consists of 66 girls in so the sample statistic of 11/24 results in a z score that is 1 standard deviation below 0. Complete parts (a) through (h) below. The test statistic is (Type an integer or a decimal.) f. What is the P-value? The p-value is 0.1557 (Round to four decimal places as needed.) g. What are the critical value(s)? The critical value(s) is/are -233. h. What is the area of the critical religion? The area is (Round to two decimal places as needed.)Explanation / Answer
Solution:-
z = - 1
The p value for z < - 1 = 0.1562
Significance level = 0.01
Critical value = - 2.33
Critical region is z < - 2.33.
