Explain what the p-value means for this problem.
O If Ho 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.
O If Ho 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.
O If Ho 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.
O If Ho 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.
