A new water fountain designed for cups/bottles has a program that is designed to
stop after it has dispensed 12 oz of water. However, several of the staff who use the
fountain have noticed that their cups are slightly lower than usual. As a test, they
obtain a random sample of 5 cups of water, and set up the null hypothesis that the
mean oz of water = 12, against the alternative that it is in fact less. If the machine
operates with a known standard deviation of 0.9 oz, which of the following best
describes a test statistics that would lead the employees to conclude their machine is
not working properly?

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.
