  1. The Orange Machine Company supplies a tool for pouring cold medicine into bottles in such a way that the standard deviation of the contents is 4.25 g. A new filling process is tested on 71 bottles and the standard deviation for this sample is 3.87 g. Use a 0.05 significance level to test the claim that the new process dispenses amounts with a standard deviation less than the standard deviation of 4.25 g for the old process. Is the new process better in the sense of dispensing amounts that are more consistent?

Show the null hypothesis, alternative hypothesis, test statistic, P-value, or critical values as well

A local winery bottles thousands of bottles of wine per season. The winery has a machine that automatically dispenses the amount of wine per bottle before aging. Each season the wine maker randomly samples 45 bottles of wine to ensure the amount of wine per bottle is 750 ml. If there is evidence that the amount is different than (less or more than) 750 ml then the winery will need to evaluate the machine and perhaps rebottle or consider selling...
