Question Answered step-by-step Please help with the answer for Z observed (part a) and part b! Image transcription textQuestion 4 of 7 0.4/1 3 . . . 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 2025 children, 1255 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 the United States who live with two parents is different from 69%. Round your answer for z to two decimal places. Zobserved 7.89 Zcritical left -196 Zcritical right 1.96 We reject the 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 is different from69%… Show moreImage transcription textQuestion 4 of 7 K 0.4/1 b. How do you explain the Type I 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 States who live with two parents is not different from 69%, when it is different from 69%. P(Type | 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 = For a = 0.04, we Ho….
