We see that the first trapezoid has a height Δx and parallel bases of length f(x0) and f(x1). Thus, the area of the first trapezoid in Figure 2.5.2 is. 1 2Δx (f(x0) + f(x1)).Use this calculator to compute the confidence interval or margin of error, assuming the sample mean most likely follows a normal distribution.
