Past experience indicates that the time required for high school seniors to complete a standardized test is a normalrandom variable with a standard deviation of 6 minutes. test the hypothesis that o = 6 against the alternative thato < 6 if arandom sample of the test times of 20 high school seniors has a standard deviation 5 = 4.51. use a 0.05 level ofsignificance.

20 points 1. 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. 2. 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+1 g(x)=2x^2+1
