One hundred individuals, aged 20-58, were given a test of psychomotor skill. Both age and score were classified in the accompanying table. Age  High  Ave  Low 40 - 59  23  20  17 20 - 39  18  12  10 Test for dependency of the scores obtained in the psychometric test and the individual’s age.  Set alpha at 5% level. State your hypothesis and show your solution and state your final conclusion.
