Answer:

p=-b+72

Step-by-step explanation:

The total number of people is the sum of the people who bring their own supplies, b, and the people who are given supplies, p, so the total number of people is p+b. It is given that there are 72 people in total so p+b+72. Subtracting b on both sides to solve for p then gives p=-b+72.

Using the t-distribution, the t-statistic for the two-sided test would be of t = 0.7.

<h3>What is the test statistic for a t-distribution hypotheses test?</h3>

The test statistic is given by:

$t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}$

The parameters are:

$\overline{x}$ is the sample mean.

$\mu$ is the expected value.

s is the standard deviation of the sample.

n is the sample size.

The values of the parameters are given as follows:

$\mu = 22, s = 7.043, n = 6$ .

The sample mean is:

$\overline{x} = \frac{23 + 35 + 17 + 30 + 20 + 19}{6} = 24$

Hence the test statistic is:

$t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}$

$t = \frac{24 - 22}{\frac{7.043}{\sqrt{6}}}$

t = 0.7.
