Random error is: A. an outside influence that affects the true score in a consistent way. B. the extent to which a measure will
produce the same results each time it is used. C. the extent to which a research method measures what it is intended to measure. D. unsystematic influence on the true score.
Let the number of adults be x, then number of male students is 1 + 7x and the number of female students is (1 + 7x)/2. x + 1 + 7x + (1 + 7x)/2 = 82 2x + 2 + 14x + 1 + 7x = 164 23x = 164 - 2 - 1 = 161 x = 161/23 = 7
Therefore, number of male students is 1 + 7(7) = 1 + 49 = 50 and the number of female students is 50/2 = 25.
