How do I get the plot below in R?
Homework Answers
Below is the R code to create this plot:
install.packages("ggplot2")
library(ggplot2)
ggplot(df, aes(x = X, y = Y)) + geom_smooth(method = "lm", se = TRUE) + geom_line(aes(y = Y + 2s), linetype = "dotted") + geom_line(aes(y = Y - 2s), linetype = "dotted")

Female: Mean: 592 Std. dev.: 94 Male: Mean:628 Std. dev.:89 Calculate the interval corresponding to one, two, and three standard deviations. Type your work showing how you obtained these intervals. Keep the endpoints of the final intervals as whole numbers and clearly label and list these three intervals in your document as shown below: 68% interval (lower value, upper value) 95% interval (lower value, upper value) 99.7% interval (lower value, upper value)

How do I interpret the p-values in terms of rejecting or failing
to reject H0 at a 95% confidence level? What does the intercept
column mean in terms of p-value? How does the p-value of the F test
compare and what does it mean? In the simple linear regression I'd
conclude age isn't related to pulmonary disease (what does
intercept p-value mean) but for the multiple regression I'd say age
and height aren't related to pulmonary disease but smoking is...
