You measure 22 randomly selected textbooks' weights, and find they have a mean weight of 36 ounces. Assume the population standard deviation is 12.6 ounces. Based on this, construct a 99% confidence interval for the true population mean textbook weight.

Negative 5 1/12 + negative 4 1/4 + 6 3/4

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.
