from scipy.stats import mannwhitneyu
x = [1, 2, 3]
y = [4, 5, 6]
stat, p = mannwhitneyu(x, y, alternative='greater')
print(stat, p)

AReplace mannwhitneyu with mann_whitney_u

BChange 'alternative' to 'two-sided'

CNo error; code runs correctly

DUse 'alternative="greater"' with capital G

Step-by-Step Solution

Solution:

Step 1: Check function parameters
The mannwhitneyu function accepts an alternative parameter with values 'two-sided', 'less', or 'greater'.
Step 2: Verify code correctness
Using alternative='greater' is valid and the function call is correct.
Final Answer:
No error; code runs correctly -> Option C
Quick Check:
Correct parameter usage = D [OK]

Quick Trick: Check scipy docs for valid 'alternative' values [OK]
