Keith tabulated the following values for time spent napping in minutes of six of his friends: 23, 35, 17, 30, 20, and 19. The st

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.

Find the distance between the two pints in simple radical form (9,3)(5,-3)

irina1246 [14]

Answer: 2sqrt(13)

Step-by-step explanation:

Using the distance formula, we get:

$\sqrt{(9-5)^{2}+(3-(-3))^{2}}=\sqrt{16+36}=\sqrt{52}=2\sqrt{13}$

And also pls write down area of the square

Arte-miy333 [17]

since it is a square, all sides are 6. and the area would be 36 because 6x6 is 36! and the perimeter is 24! Hope this helps! :)
