data sets in the table above?
- The standard deviation of data set B is larger than the standard deviation of data set A.
- The standard deviation of data set A is larger than the standard deviation of data set B.
- The standard deviation of data set A is equal to the standard deviation of data set B.
- There is not enough information available to compare the standard deviations of the two data sets.
The correct answer is: The standard deviation of data set B is larger than the standard deviation of data set A.
For set A the standard deviation is small, while comparing with the standard deviation with set B. why because in set B the data values show more variation from the mean.

The Conowingo Reservoir had an original storage capacity of 300,000 acre-feet at the end of 1928, the year in which it was built. Starting in 1929, sediment carried
downstream by the Susquehanna River collected in the reservoir and began reducing the reservoir's storage capacity at the approximate rate of 1,700 acre-feet per year.
Which of the following could be a graph of the reservoir's capacity c, in acre-feet, as a function of time t, in years, after 1928?
