Based on the answer to Q6, use the automated data analysis tools in Excel to compute the test StatistiC. "HINT* THE ORDER OF ACTUAL AND ESTIMATED MATTERS HERE AND WE NEED TO BE CAREFUL, REMEMBER THAT THE AUTOMATED EXCEL TOOL ONLY ALLOWS FOR POSITIVE VALUES OF d. 8. Based on the answer to Q6&Q Q7, use the appropriate formula to compute the p-value for this teSt. "HINT" YOU CAN ALSO GET THIS NUMBER FROM THE OUTPUT OF THE AUTOMATED ANALYSIS USED TO ANSWER Q7. 9.
