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.

Notes on how to multiply/divide with scientific notation
snow_tiger [21]

Answer:

Treat the numbers separately and powers separately.

Multiply the two results at the end.

Example:

(2×10⁵) ÷ (4×10²)

(2 ÷ 4) × (10⁵ ÷ 10²)

0.5 × 10³

5.0 × 10²

What is the length of x
Nat2105 [25]

Answer:

10 is your answer

Step-by-step explanation:

Note that the side given to us has a measurement of 5 for one of the legs of the isosceles.

This means that the <em>1</em> side on the 30-60-90 triangle has a measurement of 5.

Now, note the measurements of the triangle sides for a 30-60-90 triangle. They measure at: 1 , √3 , 2.

the side 1 is given to us, at 5. You are solving for the hypothenuse (2). Multiply 2 to the side 1

5 * 2 = 10

10 is your answer

Find the midpoint of the line segment joining the points R(3,2) and S(-5,5).
inessss [21]

The x coordinates are 3 and -5. They add to 3+(-5) = -2

Cut this in half to get -2/2 = -1

The x coordinate of the midpoint is x = -1

-------------------

The y coordinates are 2 and 5. They add to 2+5 = 7.

Then we cut this in half to get 7/2 = 3.5

The y coordinate of the midpoint is y = 3.5

-------------------

Overall, the midpoint is (-1, 3.5)

<h3>Answer: (-1, 3.5) which is the same as (-1, 7/2)</h3>
