Question 7 1 / 1 pts Use the following information to answer Questions 7 through 9. Is the ideal number of children among people under age 40 in the U.S. different compared to people from previous generations? The 2018 GSS asks respondents the question, "What do you think is the ideal number of children for a family to have?" Of the people who responded to this question, 452 were under age 40 and 900 were age 40 or older. The mean ideal number of children reported by respondents under 40 years old was 2.619 (s = 0.961), whereas the mean number of children reported by respondents age 40 and older was 2.599 (s = 0.980). What is the degrees of freedom for a significance test of the difference in mean ideal number of children reported by these two age groups? 451 899 1351 1352
