Suppose a 95% confidence interval for μ has been constructed. if it is decided to take a larger sample and to decrease the confidence level of the interval, then the resulting interval width would (assume that the sample statistics gathered would not change very much for the new sample.) a) be larger than the current interval width. b) be narrower than the current interval width. c) be the same as the current interval width. d) be unknown until actual sample sizes and reliability levels were determined.

The equation respenting the left table is

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
