Answer:

Step-by-step explanation:

Given that in order to efficiently bid on a contract, a contractor wants to be 95% confident that his error is less than two hours in estimating the average time it takes to install tile flooring.

Std deviation =4.5 errors

95% confidence interval = Mean±1.96*std dev

Hence we have

$1.96(\frac{4.5}{\sqrt{n} } )$

$\sqrt{n} \geq 4.41\\n\geq 19.4481$

Sample size should be 20.
