For this week's homework, we will revisit some old homework problems. But this time we'll use R to solve them (you must use R to do problems 1 - 5). We'll also collect a little data in class. 1) Find the following probabilities: a) Pr{Z < 4.3} b) Pr{Z > -1.69} c) Pr{-1.12 < Z < 1.12} d) Pr{-1.3 < Z < 0.98} e) Pr{Z < -1.12 or Z > 1.12} (you want the probability outside the range -2.67 to 2.67)

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
