E Exponents (ie Powers and Square Roots, etc.)

MD Multiplication and Division (left-to-right)

AS Addition and Subtraction (left-to-right)

[(30 + 6) - 32] : 9 · 2 = (36 - 32) : 9 · 2 = 4 : 9 · 2 = 4/9 · 2 = 8/9

Clinical trials involved treating flu symptoms with a new medicine. Among 724 patients treated

schepotkina [342]

According to the null hypothesis, the test statistic of the proportion is of z = 120.1.

<h3>What is the null hypothesis?</h3>

The claim is that the rate of nausea is greater than the 6% rate experienced by flu patients given a placebo. At the null hypothesis, we consider the claim as false, hence the null hypothesis is:

$H_0: p \leq 0.06$

<h3>What is the test statistic?</h3>

The test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

In which:

$\overline{p}$ is the sample proportion.

p is the proportion tested at the null hypothesis.

n is the sample size.

In this problem, the parameters are:

$p = 0.06, n = 724, \overline{p} = \frac{72}{724} = 0.0994$

Hence, the test statistic is given by:

$z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}$

$z = \frac{0.0994 - 0.06}{\sqrt{\frac{0.06(0.94)}{724}}}$

$z = 120.1$
