Question 1

Why would you use the Tukey multiple comparison?

to estimate differences in sample means


to test for normality


to estimate differences in pairwise means


to test for independence of errors



Question 2

\(\style{font-family:Times New Roman;}{{\widehat p}_1-{\widehat p}_2\dot\sim N\left(P_1-P_2,\frac{P_1(1-P_1)}{n_1}+\frac{P_2(1-P_2)}{n_2}\right)}\)

The preceding statement is true provided that:


\(\style{font-family:Times New Roman;}{{\widehat p}_1}\)follows a normal distribution.


both\(\style{font-family:Times New Roman;}{{\widehat p}_1}\)and\(\style{font-family:Times New Roman;}{{\widehat p}_2}\)follow a normal distribution.


\(\style{font-family:Times New Roman;}{n_1P_1\geq5,\;n_1\left(1-P_1\right)\geq5}\)and\(\style{font-family:Times New Roman;}{n_2P_2\geq5,\;n_2\left(1-P_2\right)\geq5}\).


\(\style{font-family:Times New Roman;}{n_1P_1\geq5,\;n_1\left(1-P_1\right)\geq5}\)or\(\style{font-family:Times New Roman;}{n_2P_2\geq5,\;n_2\left(1-P_2\right)\geq5}\).
