A medical researcher wants to determine if there is a relationship between the age group in which a patient falls and whether they show symptoms when they test positive for cooties. Given the following table, use the Chi-Square test to determine if there is a dependent relationship between age and the occurrence of symptoms. Age 0-18 years 19-60 years Over 60 No Symptoms 15 61 14 Light Symptoms 22 85 18 7) Compute the Chi-Square test statistic. Heavy Symptoms 15 57 13 8) Comparing the critical value X² = 9.488, what is your conclusion about whether there is a relationship between someone's age and the severity of their symptoms?
