Recent research suggests that college students spend an average of about 1.5 hours on social media each day. Suppose a DVC school newspaper reporter believes that DVC students spend less time than that on social media each day. After obtaining a sample of DVC students, the reporter finds that DVC students spend an average of 1.3 hours each day on social media.
1. As the reporter sets up a hypothesis test to determine if their belief is correct, what is their claim?

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.
