The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less is 0.0020

<h3>What is probability? </h3>

Probability can be defined as the likelihood of an event to occur. In statistics, the mean of the sample distribution typically shows the probability of the population.

From the parameters given:

The sample size (n) = 55 patients
Let's assume that the mean (x) = 32 (i.e. 58.2%) of the patients

The sample proportion $\mathbf{\hat p}$ can be computed by using the expression:

$\mathbf{\hat p = \dfrac{x}{n}}$

$\mathbf{\hat p = \dfrac{32}{55}}$

$\mathbf{\hat p =0.582}$

If the percentage of the probability of all patients in the emergency room = 0.75

The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less can be computed as:

$\mathbf{( \hat P \leq 0.582) = P \Big( \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}} \leq \dfrac{0.582 - 0.75}{\sqrt{\dfrac{0.75(1-0.75)}{55}}} \Big )}$

$\mathbf{( \hat P \leq 0.582 )= P \Big( Z \leq \dfrac{-0.168}{\sqrt{0.003409}} \Big )}$

$\mathbf{( \hat P \leq 0.582) = P \Big( Z \leq -2.88 \Big )}$

From the Z distribution table:

$\mathbf{( \hat P \leq 0.582) = 0.00198}$

$\mathbf{( \hat P \leq 0.582) \simeq 0.0020}$

Is Hillary Clinton’s speech “Women’s Rights Are Human Rights” a primary or secondary source?

Genrish500 [490]

Hello!

This would be considered a primary source since it came directly from Hillary Clinton. If it were a paraphrased version of her speech, for example, then it would be considered a secondary source.

I hope this helps you! have a great day!
