The quality-control manager determines that the fill levels are normally distributed with a mean of 64 ounces and a standard deviation of 0.42 ounce. He has an engineering recalibration machine in attempt to lower the standard deviation. After recalibration, the quality-control manager randomly selects 19 bottles from the line and determines that the standard deviation is 0.38 ounce. Is there less variability in the filling machine? Use a - 0.1. The null and alternative hypothesis would be: Ho : 1 = 0.38 Ho:0 = 0.38 Ho:0 - 0.42 Ho: / = 64 Ho:0 - 64 H1:u 64 H1:o
