Carry out a one-way ANOVA by hand to test the following research question: Carl wants to know if drinking beer (2, 5 or 8 beers) affects the number of times people sing karaoke at a local bar in a given night. He is predicting that the groups will differ significantly (α = .05). (Perform post-hoc tests if necessary)

One Way ANOVA (Analysis of
Variance)
A manufacturer of steel wants to test the effect of the method
of manufacture on the tensile strength of a particular type of
steel. Four different methods have been tested and the data shown
in Table 1. (Use Minitab)
Develop the ANOVA table and test the hypothesis that methods
affect the strength of the cement. Use a = 0.05
Use the Tukey’s method with a =0.05 to make
comparisons between pairs of means.
