Which of the following is an accurate statement. Insert your calculated value for "<p-value>".
If the chi-square value is greater than the critical value, accept the null hypothesis.
Based on the chi square value, which of the following is the corresponding p-value?
p<0.005
0.005<p<0.01
0.01<p<0.05
0.05<p<0.10
0.10<p<0.20
0.20<p<0.30
0.30<p<0.50
0.50<p<0.70
0.70<p<0.80
0.08<p<0.95

Reject the hypothesis
Accept the hypothesis
Accept the null hypothesis
Reject the null hypothesis
If the hypothesis is true, there is a probability of <p-value> of obtaining results at least as extreme as our results.
If the null hypothesis is true, there is a probability of <p-value> of obtaining results at least as extreme as our results.
There isn't a <p-value> chance that the hypothesis isn't not false.
