35, because if he makes 70 out of 100, you can divide that by 2 so you get 35 out of 50

35 :) If you change the percent into a decimal (0.70) and multiply that by 50, you will get the answer!

A researcher conducts a repeated-measures study to evaluate a treatment with a sample of n = 16 participants and obtains a t sta

Sedaia [141]

Answer:

Option 3) We reject the null hypothesis with one tail test and accept the null hypothesis with two tail test.

Step-by-step explanation:

We are given the following information:

n = 16

$t_{statistic} = 1.94$

$\alpha = 0.05$

Now,

Right One-tail Test

$t_{critical} \text{ at 0.05 level of significance, 15 degree of freedom } = 1.753$

$t_{stat} > t_{critical}$

We reject the null hypothesis in this case.

Two-tail Test

Now, $t_{critical} \text{ at 0.05 level of significance, 9 degree of freedom } = \pm 2.131$

$-2.131 < t_{stat} < 2.131$

We accept the null hypothesis in this case.

Option 3) We reject the null hypothesis with one tail test and accept the null hypothesis with two tail test.

Out of 132 seventh graders 33 voted math as their favorite subject. What percentage is this?

snow_lady [41]

Answer:

25%

Step-by-step explanation:

To find the percentage, we take the amount that found math as their favorite subject and divide it by the total amount of students.

33/132 = .25

This is in decimal form. To change it to percent form, multiply by 100

.25 * 100 = 25 percent

Write the equation of a line in slope-intercept form, y = mx + b, between the following

kupik [55]

Answer:

$y = \frac{3}{2} x + 2$

Step-by-step explanation:

In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.

$\boxed{slope = \frac{y1 - y2}{x1 - x2} }$

Using the formula above,

$slope = \frac{5 - ( - 4)}{2 - ( - 4)}$

$m = \frac{5 + 4}{2 + 4}$

$m = \frac{9}{6}$

$m = \frac{3}{2}$

Substitute the value of m into the equation:

$y = \frac{3}{2} x + b$

To find the value of b, substitute a pair of coordinates into the equation.

When x= 2, y= 5,

$5 = \frac{3}{2} (2) + b$

5= 3 +b

b= 5 -3

b= 2

Thus, the equation of the line is $y = \frac{3}{2} x + 2$ .
