In a study of patients to undergo surgery, an attempt is made to relate the number of days in the hospital with the age of the patients. The hospital collects the following information: • Present a scatter diagram of the information. • Find the equation of the regression line. Graph the line. • Estimate approximately how many days a 45-year-old patient would be hospitalized. • For a margin of error of 5% you could conclude that there is statistical evidence of that the linear model is the best fit for the data? • Determine the correlation coefficient. What could you interpret? • For a margin of error of 5% you could conclude that there is statistical evidence of that the data are significantly related?
