question 13

Essay

In a water-bottling facility, several machines fill plastic bottles with 16 ounces of drinking water. The following TI-84 Plus display presents the results of a one-way ANOVA to determine whether the mean fill volumes differ among the filling machines

i). State the null hypothesis.
ii). How many filling machines were involved in the study?
iii). Assume the design was balanced. How many water bottles were measured for each
filling machine?
iv). What are the values of SSTr, SSE, MSTr, and MSE? v). What is the value of the test statistic?
vi). What is the P-value?
vii). Can you conclude that the mean fill volume differs among the filling machines? Use
the α = 0.05 level of significance.
