What is the p-value output of this code?

from scipy.stats import wilcoxon
x = [5, 7, 9, 11, 13]
y = [6, 8, 10, 12, 14]
stat, p = wilcoxon(x, y, alternative='less')
print(round(p, 4))

A0.5000

B0.9688

C0.0312

D0.2500

Step-by-Step Solution

Solution:

Step 1: Understand alternative='less'
This tests if median of x is less than y.
Step 2: Calculate Wilcoxon test and p-value
Since x values are smaller, p-value is low, about 0.0312.
Final Answer:
0.0312 -> Option C
Quick Check:
Wilcoxon p-value for less alternative = 0.0312 [OK]

Quick Trick: Use alternative='less' to test if x < y median [OK]
