Instructions: The SPSS output presented below in Table 4.1 was generated from the 2021 General Social Survey (representative of the noninstitutionalized adult (18+) population in the United States). It contains summary statistics for the variable AGEKDBRN ("respondent's age in years at the birth of their first child") by the variable sex ("respondent's gender). For questions 1-3, use the mean and standard deviation for male respondents. Question 4 does not use the SPSS output. Answer the questions in complete sentences in a separate document (with question numbers but not the questions).
