The lifespan of xenon metal halide arc-discharge bulbs for aircraft landing lights is normally distributed with a mean of 1,500 hours and a standard deviation of 570 hours.
(a) If a new ballast system shows a mean life of 1,704 hours in a test on a sample of 12 prototype new bulbs, would you conclude that the new lamp’s mean life exceeds the current mean life at α = 0.05?
Yes
No
(b) What is the p-value? (Round your answer to 4 decimal places.)

1) your friend taylor missed class today and needs some identifying solutions of systems. explain to taylor where to find the solution(s) of any system using its graph 2)taylor graphs the following in desmos and decides that f(x) = g(x) at x = 0, x = 1, & x = 3. f(x) = 2x+1g(x) = 2x2+1 provide taylor some feedback that explains which part of the answer was incorrect and why.
