The survey of study habits and attitudes (ssha) is a psychological test that measures the motivation, attitudes, and study habits of college students. scores range from 0 to 200 and follow (approximately) a normal distribution, with mean of 110 and standard deviation σ = 20. you suspect that incoming freshman have a mean μ, which is different from 110 because they are often excited yet anxious about entering college. to verify your suspicion, you test the hypotheses
h0: μ = 110, ha: μ 110
you give the ssha to 50 students who are incoming freshman and find their mean score.
suppose you observed the same sample mean = 115.35, but based on a sample of 100 students. what would the corresponding p-value be?

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.
