Each of the trials wasclassified 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 ofthe cells also have blanks. Fill in these blanks with the frequencies expected if the two variables, color vision of participantand trial outcome, are independent.Round your answers to two or more decimal places.Send data to ExcelColorblindColorvision of Notparticipant colorblindTotalHit820639721Miss240270Trial outcomeFalsealarm24294279303Correctrejection746080682Total20417962000X?F8 MB)

Do colors affect mood? You are particularly interested to know which color gives people a sense of serenity and peacefulness. You conduct an experiment by making participants stay for 20 minutes inside a room painted with a particular color (e.g., Red, Orange, Yellow, Green, Blue). With the use of temperature-sensitive cameras, you record the average body temperature of each individual during their stay inside each room (i.e., lower body temperatures are associated with feelings of calmness and relaxation; higher body temperatures - stimulation, excitement). Results are presented on the table. Red Orange 39 Yellow Green Blue 43 38 33 31 39 43 39 35 34 41 44 42 34 32 42 35 39 37 32 45 40 39 36 35 41 39 38 33 34
