A) $\sigma = 6.66$
B) $\sigma = 0.98$
C) $\sigma = 7.51$
D) $\sigma = 3.39$

Quizplus · Accepted Answer

The standard deviation for a binomial distribution is calculated using the formula $\sigma = \sqrt{n \cdot p \cdot (1-p)}$. Substituting the given values, $\sigma = \sqrt{48 \cdot \frac{3}{5} \cdot \frac{2}{5}} = \sqrt{48 \cdot 0.6 \cdot 0.4} = \sqrt{11.52} \approx 3.39$.
