data(airquality)
dat <- airquality[1:120, ] Then do the full analysis on dat$Temp and dat$Day, with statement of (slope) hypothesis test and accompanying sentences and interpretation. If you would like more information on the dataset, you can look this up using ?airquality Render the document to PDF, and upload it
