We can find the area of the rectangle using the formula below.

Area = length × width

Since the length is 8 inches and the width is 6 inches, we can plug this information into the formula to get (8 in.)(6 in.)

which simplifies to 48 in.².

So the area of the rectangle is 48 in.².

Answer:

The minimum sample size required is 25 so that margin of error is no more than 3 minutes.

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 42 minutes

Standard Deviation, σ = 9 minutes.

We want to build a 90% confidence interval such that margin of error is no more than 3 minutes.

Formula for margin of error:

$z_{critical}\times \dfrac{\sigma}{\sqrt{n}}$

$z_{critical}\text{ at}~\alpha_{0.10} = 1.64$

Putting values, we get.

$z_{critical}\times \dfrac{\sigma}{\sqrt{n}}\leq 3\\\\1.64\times \dfrac{9}{\sqrt{n}}\leq 3\\\\\dfrac{1.64\times 9}{3}\leq \sqrt{n}\\\\4.92\leq \sqrt{n}\\\Rightarrow n\geq 24.2064\approx 25$

Thus, the minimum sample size required is 25 so that margin of error is no more than 3 minutes.
