◦

\(\style{font-family:Times New Roman;}{{\overset˜\mu}_1-{\overset˜\mu}_2=\Delta_{\text{o}}}\).

◦

\(\style{font-family:Times New Roman;}{\overset˜\mu={\overset˜\mu}_0}\).

◦

the sequence of observations is random.

◦

theksamples are from identical populations.

Question 2

In determining the Spearman’s rank correlation coefficient, what is done if multiple observations within either variable have the same value?

◦

As the data are assumed to be from continuous distributions, this will never happen.

◦

The observations are ignored and the sample size adjusted accordingly.

◦

The observations are given the mean rank of their positions in the ordered list.

◦

The observations are arbitrarily assigned a rank in sequence.
