poth The depletion time of a vital resource in a production process is believed to be normally distributed with a mean of u = 31 minutes and a standard deviation of a = 4 minutes. A recently appointed production team introduced new efficiencies that they claim make the depletion of the resource slower. To test this claim, a random sample of n = 10 production shifts were taken and the observed mean depletion time of the resource was = 32.3 minutes. a a. In testing the production team's claim, select the appropriate alternative hypothesis, H₁ or Ha:
