A fund manager wants to know if the annual rate of return is greater for growth stocks (sample 1) than for value stocks (sample 2). The fund manager collects data on the returns of growth and value funds. Below are the sample sizes and rank sums for the Wilcoxon rank-sum test. Using the p-value approach and α = 0.01, the appropriate conclusion is ________.
A) do not reject the null hypothesis; conclude the median return of growth stock is greater than the median return of value
B) do not reject the null hypothesis; we cannot conclude the median return of growth stock differs from the median return of value stocks
C) reject the null hypothesis; conclude the median return of growth stock is greater than the median return of value stocks
D) reject the null hypothesis; we cannot conclude the median return of growth stock is greater than the median return of value stocks
