Which of the following is the correct syntax to perform an independent t-test using SciPy?

Attest_ind(sample1, sample2)
Bttest_rel(sample1, sample2)
Cttest_ind(sample1 == sample2)
Dttest_rel(sample1, sample2, equal_var=True)
Step-by-Step Solution
Solution:

  1. Step 1: Recall function signatures

    ttest_ind takes two arrays as separate arguments to compare independent samples.

  2. Step 2: Identify correct usage

    ttest_ind(sample1, sample2) correctly calls ttest_ind(sample1, sample2). ttest_rel(sample1, sample2) uses the related test, C has invalid syntax.

  3. Final Answer:

    ttest_ind(sample1, sample2) -> Option A

  4. Quick Check:

    Independent t-test syntax = D [OK]
Quick Trick: Use ttest_ind(array1, array2) for independent samples [OK]
Common Mistakes:
MISTAKES
  • Using ttest_rel for independent samples
  • Passing a boolean expression instead of arrays
  • Incorrect parameter names
