The graph is an open circle at -1 with the line going towards the positive numbers.

First, we have to make $w$ the subject of the equation:

$w - 0.9 > -2.1\\w > -2.1 + 0.9\\w > -1.2$

This shows that $w$ is less than but not equal to $-1.2$ . So we are going to use an arrow that has a non-shaded circle. Since the symbol is the greater than symbol, or >, the arrow will point to the right. Thus, the arrow we choose will be the last arrow.

Now since we are comparing $w$ with $-1.2$ , we place the arrow above the $-1.2$ point. That's how he place the arrow in the number line.

P-value approach is used to take a decision to reject or accept the null hypothesis as indicated below:
REJECT the hypothesis, if p-value FAIL TO REJECT the hypothesis, if p-value > the alpha value.
Alpha value represents the level of significance 
If alpha value is NOT indicated: alpha = 0.05 can be assumed 

REJECT the hypothesis, because p-value (0.036) < the alpha value assumed which is 0.05

What is the slope of the line? y=54x−13π

Grace [21]

If the equation is in the form of y = mx + C, where m and C are real numbers, the slope (which means gradient) of the line is the coefficient of x (I.e. the number to the left of x in simple language), which is m.

In this case, m = 54 and C = -13pie. Both are real numbers, which means that this equation satisfies the form of y = mx + C

m is the coefficient of x, which is 54. 54 is the gradient of this line, which means that for every 54 y-axis units the line increases, the line increases 1 x-axis unit.

Hope this helps! :)

Question 6 (1.25 points)

Lisa [10]

Answer:

Test statistic Z= 1.713

The calculated Z- value = 1.7130 < 2.576 at 0.01 level of significance

Null hypothesis is accepted

There is no difference between the mean annual salary of all lawyers in a city is different from $110,000

Step-by-step explanation:

Step(i):-

A researcher wants to test if the mean annual salary of all lawyers in a city is

different from $110,000

Mean of the Population μ = $110,000

Sample size 'n' = 53

Mean of the sample x⁻ = $114,000.

standard deviation of the Population = $17,000,

Level of significance = 0.01

Null hypothesis :

There is no difference between the mean annual salary of all lawyers in a city is different from $110,000

H₀: x⁻ = μ

Alternative Hypothesis : x⁻ ≠ μ

Step(ii):-

Test statistic

$Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }$

$Z = \frac{114000-110000}{\frac{17000}{\sqrt{53} } }$

Z = 1.7130

Tabulated value Z = 2.576 at 0.01 level of significance

The calculated Z- value = 1.7130 < 2.576 at 0.01 level of significance

Null hypothesis is accepted

There is no difference between the mean annual salary of all lawyers in a city is different from $110,000
