Researchers in education are performing a study to see if listening to soothing music while taking a standardized math test increases the mean test score. The hypotheses are Ho: µ = 79 versus Ha: u > 79, and the p-value for the hypothesis test was 0.035. %3D Which of the following is the best interpretation of this p-value? o If listening to soothing music has no effect on the mean test score, the probability of obtaining the observed mean test score or something larger is 0.035. o If listening to soothing music increases the mean test score, the probability of obtaining the observed mean test score or something larger is 0.035. O There is a 3.5% chance that listening to soothing music has no effect on the mean test score. o There is a 3.5% chance that listening to soothing music increases the mean test score.

Question
**Study on the Impact of Soothing Music on Test Performance** Researchers in education are performing a study to determine if listening to soothing music while taking a standardized math test increases the mean test score. The hypotheses are: - \( H_0: \mu = 79 \) (Null Hypothesis: The mean test score is 79) - \( H_a: \mu > 79 \) (Alternative Hypothesis: The mean test score is greater than 79) The *p-value* for the hypothesis test was 0.035. **Question: Which of the following is the best interpretation of this *p-value*?** - If listening to soothing music has no effect on the mean test score, the probability of obtaining the observed mean test score or something larger is 0.035. - If listening to soothing music increases the mean test score, the probability of obtaining the observed mean test score or something larger is 0.035. - There is a 3.5% chance that listening to soothing music has no effect on the mean test score. - There is a 3.5% chance that listening to soothing music increases the mean test score.
