Question 1

The Spearman’s rank correlation coefficient is a nonparametric indicator of:

◦

the similarity between two independent samples.


◦

the correlation between the ranks of two variables.


◦

any relationship between the ranks of two or more variables.


◦

departure from normality.



Question 2

The total number of words per page is recorded from a random sample of 17 pages printed using a standard font and from 20 pages using a new font. A Wilcoxon rank-sum test is performed, and the sum of the ranks of the standard font sample (sample 1) is 301 (i.e., W = 301). Using a normal approximation, does the new font appear to increase the median number of words per page? Assume the number of words per page can be modeled as a continuous variable. Select the correctp-value and decision. (Useα= 0.05.)

◦

p= 0.9920, fail to rejectH0


◦

p= 0.0080, rejectH0


◦

p= 0.2514, fail to rejectH0


◦

p= 0.7486, fail to rejectH0
