Netflix compares average weekly viewing hours across Basic (4.2 hrs), Standard (6.8 hrs), and Premium (9.1 hrs) subscribers. A sample of 25 subscribers per plan is selected. The analysis produces an F statistic of 14.73 and a p-value of 0.000008.Hypotheses: H₀: µBasic = µStandard = µPremiumH₁: At least one group mean is significantly different At α = 0.05, what is the correct decision?

An aluminum [E = 9,750 ksi] bar is bonded to a steel [E = 30,900 ksi] bar to form a composite beam as shown. The composite beam is subjected to a bending moment of M = +334 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.630 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.2077 in.4, find the magnitude of the maximum bending stress in the steel.
