Suppose a random sample of size 36 is drawn from a population with a mean of 272. If 87% of the time the sample mean is less than 275, what is the population standard deviation? Appendix A Statistical Tables

(Round your answer to 2 decimal places, e. g. 15.25.)

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
