The two data sets in the table below are dependent random
samples. The population of (x−y)(x-y) differences is approximately
normally distributed. A claim is made that the mean difference
(x−y)(x-y) is not equal to -23.5.

Compute the area under y = √x between x = a and x = b where a
and b are user specified values obtained via cin. Account for
invalid user input cases of a < 0 and a > b. For each case of
invalid input, immediately output to the user what the error was.
Allow the user a total of three chances to enter valid input for
each input request. If the user enters incorrect input three times
in...
