Question

During a special study on learning, a psychologist found that, on the average, the rate of learning a list of special symbols in a code, N'(x), after x days of practice was given approximately by the table values below. Use left and right sums over 3 equal subintervals to approximate the area under the graph of N'(x) from x=6 to x=12. Calculate an error bound for this estimate.

x      0    2    4   6    8   10   12

N'(x) 29 26 22 20 12 11 10

The left sum, L3, is ____ The right sum R3, is ____ The error bound is ____

Explanation / Answer

The left sum, L3, is __112

The right sum R3, is 98

_ The error bound is _14_
