Using the R output in the photo, construct a 95% confidence interval for the population parameter ?1. Interpret the confidence interval.

For the following model, answer the questions given below: Im(formula = SALES ~ MEDINC, subset = -c(2, 28, 7) ) Coefficients: Estimate Std. Error t value Pr(> It1 ) (Intercept) -13187.40 3700.68 -3.564 0.00088 *** MEDINC 420.25 81.63 5.148 5.6e-06 *** Residual standard error: 5106 on 45 degrees of freedom Multiple R-squared: 0.3707, Adjusted R-squared: 0.3567 F-statistic: 26.51 on 1 and 45 DF, p-value: 5.604e-06
