This experiment examines the performance, as measured by the number of errors made, on a motor skills task. 24 subjects, 12 young and 12 old, were assigned to either an easy or hard motor skills task. There were 2 factors in the study: age (young/old) and difficulty of the motor skills task (easy/hard). The number of errors made on the motor skills task was recorded for each person and is presented in the table below. Null and Alternative Hypotheses: H0: There is not an interaction between young and old H0: µYoung = µOld H1: There is an interaction between young and old H1: µYoung ≠ µOld H0: There is not an interaction between easy and hard H0: µEasy = µHard H1: There is an interaction between young and old H1: µEasy ≠ µHard H0: There is not an interaction between age and difficulty H0: µAge = µDifficulty H1: There is an interaction between age and difficulty. H1: µAge ≠ µDifficulty My question: Report the results of the hypothesis tests below. Be sure to express the results in the context of the study and use APA format.
