Answer:

The answer is "1110, 20.4, and 31.408"

Step-by-step explanation:

For point a:

Given:

$\to mean\ ( \bar{x})=1051\\\\\to standard \ deviation \ (\sigma)=194\\\\\to P(Z$

Calculating the SAT score:

$=1051+0.3055 \times 194 \\\\ =1110.267 \approx 1110$

For point b:

Given:

$\to mean \ \bar{x}=19\\\\ \to standard \ deviation \ (\sigma) =4.7\\\\$

Calculating the equivalent ACT score:

$=19+0.3055 \times 4.7 \\\\ =20.43585 \approx 20.4$

For point c:

$\to SAT \ Score =1563\\\\\to z=\frac{(1563-1051)}{194}= \frac{512}{194}=2.64\\\\$

Calculating equivalent ACT score:

$=19+2.64 \times 4.7 \\\\=31.408$

The answer is 28.
