QuestionFind scores at 1, 2, and 3 standard deviations above the mean for: a. $\mu=13.2$, $\sigma=4.2$; b. $\mu=86.1$, $\sigma=12.5$; c. $\mu=521.4$, $\sigma=81.7$.

Studdy Solution
Calculate the score three standard deviations above the mean for problem c.
$$Score =521.4 +3 \times81.7 =766.5$$The scores one, two, and three standard deviations above the mean area.17.4,21.6,25.8b.98.6,111.1,123.6c.603.1,684.8,766.5
