Use this data to test the null hypothesis that a political candidate from such a family is equally likely to be in any one of the four ordinal positions. (Use a = 0.05.) Calculate the test statistic. (Round your answer to two decimal places.) What can be said about the P-value for the test? O P-value < 0.005 0.005 P-value < 0.01 O 0.01 < P-value <0.025 O 0.025 <P-value < 0.05 O 0.05 <P-value <0.10 O P-value>0.10 State the conclusion in the problem context. O Reject Ho. There is no evidence that a candidate from such a family is more likely to be in one ordinal position than another. O Fail to reject Ho. There is no evidence that a candidate from such a family is more likely to be in one ordinal position than another. O Reject Ho.
