Question

Question 5

    When you reject the null hypothesis for the relationship between age and opinions on abortion, you are saying:

1. There is a relationship between age and opinions on abortion in the population.
2. There is not a relationship between age and opinions on abortion in the population.
3. You are saying nothing about the population.
4. You are saying that the measure of association between age and opinions on abortion in the population is 0.

Question 6

If your Phi measure of association has a significance of .021, would you accept or reject the null hypothesis at the 95% confidence level?

1. Reject
2. Accept
3. Both accept and reject the null.
4. Neither accept or reject the null.

Question 7

   If in testing the null hypothesis at the 95% confidence level you rejected the null hypothesis in question 6, what is the probability you are wrong and that the null hypothesis is true?

1. 0%
2. 1%
3. 5%
4. 50%

Question 8

If your Phi measure of association has a significance of .021, would you accept or reject the null hypothesis at the 99% confidence level?

1. Reject Null
2. Accept Null
3. Both Accept and Reject Null
4. Neither Accept or Reject Null

Answer 1

5) since we rejected the null hypothesis then the result is significant.

We can conclude that there is relationship between age and opinion on abortion in the population.

Option a

6) if , p value < Alfa , then we reject the null hypothesis and the result is significant.

From the given data , p value = 0.021

Alfa = 0.05

So, p value < 0.05 we reject the null hypothesis.

Answer : reject null

7) which means reject the null hypothesis when actually it is true.

So , probability value = 0.05

Answer : 5%

8) given , p value = 0.021

Let Los be Alfa = 0.01

Since, p value > 0.01 we fail to reject the null hypothesis.

Answer : accept null
