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