Answer:

D is correct

Step-by-step explanation:

C is incorrect.  7/8 is incorrect because a fraction that isn't greater than a whole will result in the whole number becoming more than itself. In this case, the number 4 will become more if it is mutiplied with a fraction less than one. Multiply the numbers

<h3>4 ⋅ 7 /8 = 28/8</h3><h3>28/8 / 7/2 = 7/2</h3><h3>7/2 simplified is 6 1/2.</h3>

B is also incorrect. It'll equal 4 8/17

A is also incorrect, it equals 9/ 2, 8 1/2.

<h2>Therefore D is correct. </h2>

In a clinical test with 2161 subjects, 1214 showed improvement from the treatment. Find the margin of error for the 95% confiden
Vlad [161]

Answer:

The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.

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 z-score that has a p-value of 1 - \frac{\alpha}{2}.

The margin of error is of:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.

This means that n = 2161, \pi = \frac{1214}{2161} = 0.5618

95% confidence level

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

Margin of error:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

M = 1.96\sqrt{\frac{0.5618*0.4382}{2161}}

M = 0.0209

The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
