Help complete the table for the equation y= x - 2. Then use the table to graph the equation.
Goryan [66]

Answer:

-4, -3, -2, -1, 0

Step-by-step explanation:

Using the equation y = x -2, substitute the values for x into the equation and solve for y.

y = -2 -2

y = -4

y = -1 - 2

y= -3

y = 0 - 2

y = -2

y = 1 - 2

y = -1

y = 2 - 2

y = 0

You will have the coordinates when you plug the numbers into the table. (-2, -4), (-1, -3), (0, -2), (1, -1), (2, 0). Plot the points and connect with a line.

A study was conducted to determine whether magnets were effective in treating pain. The values represent measurements of pain us
gregori [183]

Answer and Step-by-step explanation: The null and alternative hypothesis for this test are:

H_{0}: s_{1}^{2} = s_{2}^{2}

H_{a}: s_{1}^{2} > s_{2}^{2}

To test it, use F-test statistics and compare variances of each treatment.

Calculate F-value:

F=\frac{s^{2}_{1}}{s^{2}_{2}}

F=\frac{1.26^{2}}{0.93^{2}}

F=\frac{1.5876}{0.8649}

F = 1.8356

The <u>critical value of F</u> is given by a F-distribution table with:

degree of freedom (row): 20 - 1 = 19

degree of freedom (column): 20 - 1 = 19

And a significance level: α = 0.05

F_{critical} = 2.2341

Comparing both values of F:

1.856 < 2.2341

i.e. F-value calculated is less than F-value of the table.

Therefore, failed to reject H_{0}, meaning there is <u>no sufficient data to support the claim</u> that sham treatment have pain reductions which vary more than for those using magnets treatment.
