According to the U.S. Census Bureau, 69% of children under the age of 18 years in the United States lived with two parents in 2009. Suppose that in a recent sample of 1925 children, 1215 were living with two parents.a. Using the critical value approach and significance level=0.02, test whether the current percentage of all children under the age of 18 years in the United States who live with two parents is different from 69%.Enter the critical values in increasing order. Round your answer for z to two decimal places.OBSERVED Z=?CRITICAL VALUE=?CRITICAL VALUE=?b. What is the probability of making a type one error from part a?P(TYPE ONE ERROR)=?c. Calculate the p-value for the test from part a.P-VALUE=?
