Step-by-step explanation:
False
Answer:
Change the equation to slope intercept form.
(y= 1.2x + 2.2) or (b= 1.2a + 2.2)
Then shade above the line.
Step-by-step explanation:
Let's say A is "x", and B is "y."
Change the equation to slope intercept form.
120x + 100y = 220.
(Move 120x to the other side of the equation by subtracting 120x from both sides)
100y= -120x +220
(Divide 100y by 100 to remove it from Y, divide the entire right side of the equation by 100)
y= -120x/100 + 220/100
y <= 1.2x + 2.2 -> (b= 1.2a + 2.2)
The new equation is much easier to graph.
THEN, Plot the new equation, since the sign is <= (greater than or equal to)
Make a solid line.
Then shade above the line whatever color necessary, since the sign is also "greater than"
Answer:
Step-by-step explanation:
Hello!
The hypothesis tested where that "adds produce no change" symbolically p=0.7 versus "negatives are below 70%" symbolically: p < 0.70
So the hypothesis tested where:
H₀: p=0.7
H₁: p < 0.70
After conducting the analysis the p-value was 0.291
To decide over a hypothesis test using the p-value you have to compare it with the significance level of the test. The decision rule is the following:
If p-value > α, the decision is to not reject the null hypothesis.
If p-value ≤ α, the decision is to reject the null hypothesis.
Let's say the significance level of the test is α= 0.05
Using this level the decision is to nor reject the null hypothesis.
This means that after the political ad campaign the proportion of negatives hasn't changed.
I hope it helps!
