Question 12 The following contingency table gives a summary of the data from 2000 trials of a visual experiment. Each of the trials was classified according to two variables: color vision of the participant ("Colorblind" or "Not colorblind") and trial outcome ("Hit", "Miss", "False alarm", or "Correct rejection"). In the cells of the table are the respective observed frequencies, and three of the cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, color vision of participant and trial outcome, are independent. Round your answers to two or more decimal places.
