Question

A. Direction: Find the sample proportion. (Show your complete solution.)

1. n = 550, x = 308

2. n = 480, x = 168

3. n = 620, x = 248

4. n = 740, x = 259

5. n = 1,120, x = 616

Answer 1

$P=\frac{x}{n}$

1. $P=\frac{308}{550}=0.56$

2. $P=\frac{168}{480}=0.35$

3. $P=\frac{248}{620}=0.4$

4. $P=\frac{259}{740}=0.35$

5. $P=\frac{616}{1120}=0.55$
