The contingency table below summarizes the closing price information for 500 NASDAQ stocks from last Monday, Tuesday, and Wednesday. Each of the 500 stocks are classified according to two variables: closing price movement from Monday to Tuesday ("Closing price up on Tuesday" or "Closing price not up on Tuesday") and closing price movement from Tuesday to Wednesday ("Closing price up on Wednesday" or "Closing price not up on Wednesday"). In the cells of the table are the respective observed frequencies; in addition, three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, closing price movement from Monday to Tuesday and closing price movement from Tuesday to Wednesday, are independent. Round your answers to two or more decimal places. Send data to Excel Closing price movement from Tuesday to Wednesday X Closing price Closing price up on not up on Total Wednesday Wednesday Closing price 146 131 up on 277 Tuesday Closing price movement Closing price 101 122 from Monday not up on 223 to Tuesday Tuesday Total 247 253 500
