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 2000 children, 1249 were living with two parents.a. Using the critical value approach and a = 0.05, test whether the current percentage of all children under the age of 18 years in theUnited States who live with two parents is different from 69%.Round your answer for z to two decimal places.Zobserved =iZcritical left =iZcritical rightiWethe null hypothesis.We conclude that the current percentage of all children under the age of 18 years in the United States who live with two parents is69%.b. How do you explain the TypeI error in part a? What is the probability of making this error in part a?The Type I error occurs when we conclude that the current percentage of all children under the age of 18 years in the United Stateswho live with two parents is69%, when it is69%.P(Type I error) =c. Calculate the p-value for the test of part a. What is your conclusion if a = 0.04?Round your answer for the p-value to four decimal places.p-value =iFor a = 0.04, wev Ho.
