9. How many levels were used in the experiment? An experiment was described to determine the effect of C2F6 flow rate on the uniformity of the etch on a siliconwafer used in integrated circuit manufacturing. The resulting table of random sampling is shown.ObservationsC₂F6 Flow(SCCM)1234561252.74.6 2.63.03.23.81604.94.6 5.0 4.23.64.22004.63.42.93.5 4.15.1

You intend to conduct an ANOVA with 31 subjects, which will be divided into 3 treatment groups. (Because it will be impossible to have equal sized groups, this is referred to as an "unbalanced" single-factor ANOVA.)
