Part (a) A phone company determine that a higher income indicates that a customer has more expensive calling plan. what does the analysis show?
option 1: There is no correlation between income and calling price plan.
option 2: there is a correlation between income and calling plan price. there may or may not be causation. further studies would have to be done to determine this.
Option 3: there is a correlation between income and calling plan price. there is probably also causation. this is because there is an increase in the calling plan price with an increase in income.

Part (b) a wine store conducted a study. it showed that a customer does not tend to buy more or fewer bottles when more samples are offered. what can we conclude.
option 1: there is no correlation between number of bottles bought and number of samples offered.
option 3: there is no correlation between number of bottles bought and number of samples offered. however, there is no causation. this is because there is probably an increase in number of bottles bought with an increase in number of samples.
option 3: there is a correlation between number bottles by and number of samples offered. there may or may not be causation. further studies would have to be done to determine this.

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.
