In order to officailly bid on a contract, a contractor wants to be 95% confident that his error is less than two hours in estima

iVinArrow [24]

Answer: 20

Step-by-step explanation:

Formula to find the sample size : $n=(\dfrac{\sigma\times z_{\alpha/2}}{E})^2$

Given : Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

Margin of error : $E$

Standard deviation: $\sigma=\text{ 4.5 hours}$

Then, we have

$n=(\dfrac{4.5\times(1.96)}{2})^2=19.4481\approx20$

Hence, the minimum sample size must be 20.
