During 2002,.34 (i.e., 34%) of the births to teenage mothers in the U.S. were to unmarried women. To determine if this proportion differs for Americans of Japanese descent, a random sample is obtained of 112 American teenage women of Japanese descent who give birth. The number of these women who are unmarried is found to be 10. Determine if the proportion of births to unmarried teenagers of Japanese descent differs from that of the U.S. population in general in 2002.
