Step-by-step explanation:
The number 10 Is Rational
Point estimate (average) = $750
Standard deviation = $85
P(X>$825) = ?
Z = (X-mean)/Standard deviation = (825-750)/85 ≈ 0.88
From Z-table, P(X=825) = 0.8106
Therefore,
P(X>$825) = 1 - P(X=$825) = 1-0.8106 = 0.1894 = 18.94%
Percentage of teachers earning more than $825 is 18.94%.
