Question 1

The pooled estimate for the common variance,\(\style{font-family:Times New Roman;}{s_p^2,}\) is the weighted average of the two sample variances, where the weights are determined by:

◦

the sample standard deviations.

◦

the sample variances.

◦

the sample sizes.

◦

the sample means.

Question 2

The relationship\(\style{font-family:Times New Roman;}{\mu_1-\mu_2>0}\)may be equivalently expressed as:

◦

\(\style{font-family:Times New Roman;}{\mu_1>\mu_2}\).

◦

\(\style{font-family:Times New Roman;}{\mu_1-\mu_2=0}\).

◦

\(\style{font-family:Times New Roman}{\mu_1<\mu_2}\).

◦

\(\style{font-family:Times New Roman}{2\mu_1<2\mu_2}\).
