Hi, in need of a little assistance.Question: calculate the internal area of the living room.

Dominik [7]

The living room is rectangular. We would find the area by applying the formula for calculating the area of a rectangle which is expressed as

Area = length x width

From the information given,

internal length = 5.2

internal width = 2.95

Thus,

internal area of the living room = 5.2 x 2.95

internal area of the living room = 15.34 m^2

A study showed that 14 of 180 publicly traded business services companies failed a test for compliance with Sarbanes-Oxley requi

Vika [28.1K]

Answer:

The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 180, \pi = \frac{14}{180} = 0.0778$

95% confidence level

So $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2} = 0.975$ , so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.0778 - 1.96\sqrt{\frac{0.0778*0.9222}{180}} = 0.0387$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.0778 + 1.96\sqrt{\frac{0.0778*0.9222}{180}} = 0.1169$

The 95% confidence interval for the overall noncompliance proportion is (0.0387, 0.1169).

I really need the answer to this. Date: 04/25/17

dimaraw [331]

The answer is

I know this because I did (4 x 11 x 30) + (7 x 20 x 11)

This is also equal to 1320 + 1540 = 2860. Hope this helped!
