In six test runs, a truck operated 8, 10, 15, 7, 9, and 11miles with one gallon of gasoline. At the 95% level of confidence, is this sufficient evidence to show that the truck is operating at a mean rate of about 13.1 miles per gallon (Confidence Interval)?

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above
