Access the data about sea levels, which are available at MyMathLab and at the Pearson Downloadable Student Resources for Math & Stats website. Did you know that the sea level varies around the Earth and is increasing at different rates? For example, the sea level along the West Coast of the United States is greater than the sea level along the East Coast.
a. Construct relative frequency histograms of the sea levels since 1900 at The Battery (in New York) and at San Francisco.
b. Describe the shapes of The Battery and San Francisco distributions.
c. Compute the means of the two distributions. Compare your results. What does your comparison mean in this situation?
d. Compute the standard deviations of the two distributions. Compare your results. What does your comparison mean in this situation?
e. Due to climate change over the past century, the annual mean sea level at The Battery has increased by about 2.1 feet and the annual mean sea level at San Francisco has in- creased by about 0.6 feet. Does this help explain the comparison you made in part(d)? Explain.
f. How is it possible for the mean of The Battery distribution to be less than the mean of the San Francisco distribution even though the annual mean sea level at The Battery has increased in the past century by more than 3 times as much as at San Francisco?
