Use the given information to find the P-value. Also, use a 0.05 significance level and state the conclusion about the null hypot
Nina [5.8K]

Answer: a. 0.1031; fail to reject the null hypothesis

Step-by-step explanation:

Given: Significance level : \alpha=0.05

The test statistic in a two-tailed test is z = -1.63.

The P-value for two-tailed test : 2P(Z>|z|)=2P(Z>|-1.63|)=0.1031 [By p-value table]

Since, 0.1031 > 0.05

i.e. p-value > \alpha

So, we fail to reject the null hypothesis. [When p<\alpha then we reject null hypothesis  ]

So, the correct option is a. 0.1031; fail to reject the null hypothesis.

What’s the measure of angle c?<br><br><br> Some please answer fast. Please.
kow [346]

Answer: 42

Step-by-step explanation:

Ok what you want to do is add all of them up and equal it to 180 because a triangle is 180 degrees .

Your equation should look like this

9x-3+22x+1+42-3x = 180

What you want to do first is combine all the x and numbers on the left side so it should look like this

1) 28x+40= 180

Then you want to subtract 40 on both sides so it will look like this

2)28x=140

You want to get x by it self so you divide 28 on both sides

3) x=140/28

4) x=5

Since you are finding c you have to insert 5 into x

1) 9(5)-3

2)45-3

Then your answer should be 42
