In a study of 775 randomly selected medical malpractice​lawsuits, it was found that 502 of them were dropped or dismissed. Use a
bulgar [2K]

By using a 0.05 significance level, we can conclude that there is sufficient evidence that most medical malpractice lawsuits are dropped or dismissed.

<h3>How to test the claim for the medical malpractice lawsuits?</h3>

Since we have to compare whether the sample proportion is greater than or lesser than the population proportion, a one-tailed test would be used. Also, we would calculate the sample proportion of medical malpractice lawsuits that are dropped or dismissed as follows:

Sample proportion, p = x/n

Sample proportion, p = 502/775

Sample proportion, p = 0.6477

Mathematically, the null and alternative hypothesis is given by:

H₀: p = 0.5

H₁: p > 0.5

For the test statistic can be calculated by using this mathematical expression:

z=\frac{\hat{p}\;-\;p_o}{\sqrt{\frac{p_o(1-p_o)}{n }}  }

Where:

  • \hat{p} represents the sample mean.
  • p_o represents the mean.
  • n represents the number of subjects.

Substituting the given parameters into the formula, we have;

z = (0.6477 - 0.5)/√(0.5(1 - 0.5)/775)

z = 0.1477/√(0.25/775)

z = 0.1477/0.01796

z = 8.224.

For the p-value, we have:

p(z>8.224) = 0.0000

Therefore, the p-value (0.000) is less than the significance level α = 0.05. Based on this, we would reject the null hypothesis.

The sum of twice a number and 13 is 75 <br> • <br> but in an algebraic equation<br> DONT SOLVE
Alchen [17]

Answer:

I won't solve it, because you asked me to.

Step-by-step explanation:

The first question we should ask ourselves is "what are we looking to solve?"

We are looking for some sort of value that satisfies that equation. We'll call it x

Reading from left to right:

The sum of twice a number and 13 is 75

         +            2              x              13 = 75

2x + 13 = 75
