What is the p-value? (Round your answer to four decimal places.)
1/2(p-value)
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 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 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.
Part (g)
Sketch a picture of this situation. Label and scale the horizontal axis, and shade the region(s) corresponding to the p-value.
