question 36

Essay

Perform the required chi-square hypothesis test. Preliminary data analyses and other information indicate that it isreasonable to assume that the variable under consideration is normally distributed. Use the critical-value approach or theP-value approach as indicated.
-A machine dispenses a liquid drug into bottles in such a way that the standard deviation of the contents is 81 milliliters. A new machine is tested on a sample of 24 containers and the standard deviation for this sample group is found to be 26 milliliters. At the 5% level of significance, do the data provide sufficient evidence to conclude that the standard deviation, $\sigma _ {,}$ of the amounts dispensed by the new machine is less than 81 milliliters? Use the critical-value approach.
