Given that the heights are normally distributed, we have:
\(P(X < 10) = \frac{48}{500} = 0.096\)
Using the standard normal distribution table, \(z = -1.305\) for \(P(Z < z) = 0.096\).
Similarly, \(P(X > 24) = \frac{76}{500} = 0.152\)
Using the standard normal distribution table, \(z = 1.028\) for \(P(Z > z) = 0.152\).
We form the equations:
\(10 - \mu = -1.305\sigma\)
\(24 - \mu = 1.028\sigma\)
Subtracting these equations gives:
\(14 = 2.333\sigma\)
Solving for \(\sigma\), we get:
\(\sigma = \frac{14}{2.333} = 6.00\)
Substituting \(\sigma = 6.00\) back into one of the equations:
\(10 - \mu = -1.305 \times 6.00\)
\(10 - \mu = -7.83\)
\(\mu = 17.83\)
Thus, the mean \(\mu\) is approximately 17.8 and the standard deviation \(\sigma\) is 6.00.
