When designing a study to determine this population proportion, what is the minimum number of drivers you would need to survey t

Vlada [557]

Answer: 601

Step-by-step explanation:

The formula to find the minimum sample size(n) , if the prior population proportion is unknown:

$n=0.25(\dfrac{z^c}{E})^2$ , where E = margin of error , $z^c$ = critical z-value for confidence level c.

Given : E = 0.04

Z-value for 95% confidence = 1.96

So, the minimum sample size required = $0.25(\dfrac{1.96}{0.04})^2=0.25(49)^2$

$= 0.25\times 2401=600.25\approx601$

Hence, the minimum sample size required = 601

rodikova [14]

$10.71

Explanation

Step 1

you can easily solve this by using a rule of three.

Let

x represents the money Eileen will pay if her bag weighs 63 pounds

the proportion is the same

then

$\frac{7.14}{42}=\frac{x}{63}$

Step 2

solve for x

$\begin{gathered} \frac{7.14}{42}=\frac{x}{63} \\ 63\cdot7.14=42x \\ x=\frac{63\cdot7.14}{42} \\ x=\frac{449.82}{42} \\ x=10.71 \\ \end{gathered}$

I hope this helps you
