Older Siblings (Example 3) At a small four-year college, some psychology students were asked whether or not they had at least one older sibling. The table shows the results for men and women and shows some of the totals.
a. Calculate the totals that are not shown, and report them in the table.
b. What percentage of the men had an older sibling?
c. What percentage of the men did not have an older sibling?
d. What percentage of the women had an older sibling?
e. What percentage of the people had an older sibling?
f. What percentage of the people with an older sibling were women?
g. Suppose that in a group of 600 women, the percentage who have an older sibling is the same as in the sample here. How many of the 600 women would have an older sibling?
