The table to the right classifies a stock's price change as up, down, or no change for both today's Price and yesterday's prices. Price changes were examined for 111 days. A financial theory states that Change the price change of today for a stock must be independent of yesterday's price change. Test the hypothesis that daily stock price changes for this stock are independent. Let a = 0.025. Price Change Previous Day Up No Change Down Today Up No Change 9 Down 11 18 15 6 16 13 14 Determine the null and alternative hypotheses for the test. Choose the correct answer below. O A. Ho: Today's price change and yesterday's price change are not independent. HA: Today's price change and yesterday's price change are independent. O B. Ho: Today's price change and yesterday's price change have equal proportions. HA: Today's price change and yesterday's price change have non-equal proportions. O C. Ho: Today's price change and yesterday's price change have non-equal proportions. HA: Today's price change and yesterday's price change have equal proportions. O D. Ho: Today's price change and yesterday's price change are independent. HA: Today's price change and yesterday's price change are not independent. Calculate the test statistic. x = (Round to four decimal places as needed.) Calculate the p-value. p-value = (Round to four decimal places as needed.) Determine a conclusion. Choose the correct answer below. O A. Reject Ho. There is insufficient evidence to conclude that today's price change and yesterday's price change are not independent. O B. Reject Ho. There is sufficient evidence to conclude that today's price change and yesterday's price change are not independent. O C. Do not reject Ho. There is sufficient evidence to conclude that today's price change and yesterday's price change are not independent. O D. Do not reject Ho.
