The mean age at first marriage for respondents in a survey is 23.33, with a standard deviation of 6.13. Suppose that the proportion of area between the mean and two Z scores of ±0.35 is 0.14. Calculate the raw scores associated with these two Z scores. What proportion of respondents were first married between these two ages?
What will be an ideal response?
.25.5; 0.14 + 0.14 = 0.28
