No opinion | 16 | 42 | 17 | 18 | 93 |
Column Total | 119 | 709 | 81 | 325 | 1234 |
The p-value < 0.001
Which option best explains what the p-value means for this problem?
a) If H0 is true, then there is a chance equal to the p-value that the value of the test statistic will be equal to or less than the calculated value.
b) If H0 is true, then there is a chance equal to the p-value that the value of the test statistic will be equal to or greater than the calculated value.
c) If H0 is false, then there is a chance equal to the p-value that the value of the test statistic will be equal to or less than the calculated value
d) If H0 is false, then there is a chance equal to the p-value that the value of the test statistic will be equal to or greater than the calculated value
