Suppose m1 and m2 are true mean stopping distances at 50 mph for cars of a certain type equipped with two different types of braking systems. use the two-sample t test at significance level .01 to test h0: m1- m2 =-10 versus ha: m1 − m2 < −10 for the following data: m = 6, x =115.7, s1 = 5.03, n 5 6, y = 129.3, and s2 = 5.38. calculate the test statistic and determine the p-value.

Question 1 (50 points) your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. question 2 (50 points) taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1g(x)=2x2+1
