For a 2-tailed hypothesis test on the mean (µ) where H0: µ = 100 g and H1: µ ≠ 100g, we ended up with a confidence interval for the mean (µ) weight (g) of (89.4, 99.7). From this confidence interval, what is your decision regarding the null hypothesis?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
