Use the Midpoint Rule and the given data to estimate the value of the integral I. (Give the answer to two decimal places.)
I= ∫3.20f(x)dx
x f(x) x f(x)
0.0 8.8 2.0 7.3
0.4 8.9 2.4 8.1
0.8 6.7 2.8 7.6
1.2 8.1 3.2 7.3
1.6 8.7
If it is known that −5≤f"(x)≤1for all x, estimate the error involved in the approximation in part (a).
