Parents with sick toddlers often ask their doctors to prescribe antibiotics, but is this an effective treatment? Suppose we were particularly interested in whether children suffering from sore throats would recover faster if treated with antibiotics. A sample of 60 children is randomly selected to test if antibiotics are effective in reducing the length (measured by days) of specific illnesses. Using the Excel outputs below, answer the following questions: F-Test Two-Sample for Variances Placebo Antibiotic Mean 41.8356 35.5666 Variance 42.3033 139.6333 Observations 30 30 Df 29 29 0.30296 P(F
