Using the same data set,the probability that a student bought the coffee is?

Multiple Choice

Answer:

Administrators 19 26 4
Students 30 10 11
Selecting one cup sold at random,the probability that it will be a large cup is?

Multiple Choice

Answer:

A two-way ANOVA is conducted and the error sum of squares is worked out as 140.59.If the researcher chooses to ignore one of the factors and perform a one-way ANOVA with the same data,the error sum of squares will be smaller than 140.59.
