Streams Researchers collected samples of water fromstreams in the Adirondack Mountains to look for anydifferences in the effects of acid rain. They measured thepH (acidity) of the water and classified the streams withrespect to the kind of substrate (type of rock over whichthey flow). A lower pH means the water is more acidic.
Here is a plot of the pH of the streams by substrate (lime-stone, mixed, or shale):
Here are selected parts of a software analysis comparingthe pH of streams with limestone and shale substrates:

The peak flow rate of a person is the fastest rate at which the person can expel air after taking a deep breath.Peak flow rate is measured in units of liters per minute and gives an indication of the person’s respiratoryhealth. Researchers measured peak flow rate and height for each of a sample of 17 men. The results are givenin the table. (image included)
a. Create a scatterplot displaying the relationship between peak flow rate and height.b. Calculate the sample correlation coefficient for peak flow rate and height.c. If we were to predict the peak flow rate using height with a least-squares regression model, whatis the slope estimate ˆb?d. Continuing with part a, what is the intercept estimate ˆa?e. Based on the regression model, what is the predicted peak flow rate for a subject that is 175cmtall?f. Looking at the original data, subject 8 is 175cm tall with a peak flow rate of 670l/min. What isthe residual for this subject?g. Fit the least-squares model in R. What is the…
