Question 974851: The mean age at first marriage for respondents in a survey is 23.33, with a standard deviation of 6.13. The Z score associated with a particular age at first marriage is 0.35. If the proportion of the area between this particular age at first marriage and the mean is 0.14, what proportion of respondents experienced their first marriage earlier than this age? Your answer should be rounded to 2 decimal places, like 8.24 or 0.32. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! z-score is 0.35, and the probability is 0.64 from both the z-table and the problem (0.14 + 0.50mean).
0.64 or 64% of people were married earlier than this age.
