A study was conducted to investigate if a person's age is a significant factor in alleviating flu symptoms. Data was collected from a random sample of 150 adults who had the flu, with the primary variable of interest being the number of days it took for them to recover from all flu symptoms after receiving the same antiviral drug. The results of a simple linear model are presented below: Estimates SE t value Pr(>t) Intercept -5.20 4.51 1.15 0.2520 Age (years) 0.49 0.11 4.45 0.0348 Questions: 1) Is there a significant linear relationship between a person's age and the number of days it took them to recover from all flu symptoms?
