Questions: (a) Transform the statistics test score to a z-score. z=2.17 (Type an integer or decimal rounded to the nearest hundredth as needed.) Transform the biology test score to a z-score. z=0.77 (Type an integer or decimal rounded to the nearest hundredth as needed.) (b) Determine on which test the student had a better score. Choose the correct answer below. On the biology test the student had a better score. On the statistics test the student had a better score. The scores on both tests are the same.

Solution Steps

Step 1: Transforming the Statistics Test Score

The z-score for the statistics test is given as: \[ z = 2.17 \]

Step 2: Transforming the Biology Test Score

The z-score for the biology test is given as: \[ z = 0.77 \]

Step 3: Comparing the Test Scores

To determine which test the student performed better on, we compare the z-scores:

  • For the statistics test: \( z = 2.17 \)
  • For the biology test: \( z = 0.77 \)

Since \( 2.17 > 0.77 \), the student had a better score on the statistics test.

Final Answer

The answer is: \\(\boxed{\text{On the statistics test the student had a better score.}}\\)
