Answer
Original: μ = 76, σ =12
Standardized : μ = 100, σ =20
a.X=61
$\frac{61-76}{12} $ = $\frac{X-100}{20}$
New X = 20(-1.25) +100
= 700
b. X=70
$\frac{70-76}{12} $ = $\frac{X-100}{20}$
New X = 20(-0.5) +100
= 90
c. X=85
$\frac{85-76}{12} $ = $\frac{X-100}{20}$
New X = 20(0.75) +100
= 115
d. X=94
$\frac{94-76}{12} $ = $\frac{X-100}{20}$
New X = 20(1.5) +100
= 130
