Papessa [141]

The table is missing in the question. The table is provided here :

Group 1 Group 2

34.86 64.14 mean

21.99 20.46 standard deviation

7 7 n

Solution :

a). The IV or independent variable = Group 1

The DV or the dependent variable = Group 2

b).

$H_0: \mu_1 = \mu_2$

$H_a:\mu_1 < \mu_2$

Therefore, $t = \frac{\bar x_1 - \bar x_2}{\sqrt{\frac{s_1^2}{n_1}+\frac{S_2^2}{n_2}}}$

$t = \frac{34.86 - 64.14}{\sqrt{\frac{21.99^2}{7}+\frac{20.46^2}{7}}}$

t = -2.579143

Now, $df = min(n_1 - 1, n_2 - 1)$

df = 7 - 1

= 6

Therefore the value of p :

$=T.DIST(-2.579143,6,TRUE)$

= 0.020908803

The p value is 0.0209

$p< 0.05$

So we reject the null hypothesis and conclude that $\mu_1 < \mu_2$

What is the slope of the line shown in the graph below?

Flauer [41]

Slope = (y2-y1)/(x2-x1)
The points: (2,0) and (0,3)
(3-0)/(0-2) = 3/-2 = -3/2
The solution is -3/2

What is the value of b? IT 3b b+52 Н G j b =

cluponka [151]

b=26

Explanation

Step 1

we have two equals triangles, because

$\begin{gathered} HG=GJ \\ \text{and} \\ GI\text{ is a common side for both triangles} \end{gathered}$

then, the hypotenuses are equal

$3b=b+52$

"is step 1 clear?

Step 2

solve the equation

$\begin{gathered} 3b=b+52 \\ \text{subtract b in both sides} \\ 3b-b=b+52-b \\ 2b=52 \\ \text{divide both sides by 2} \\ \frac{2b}{2}=\frac{52}{2} \\ b=26 \end{gathered}$
