Given the scores and the claim that the average is 83, the p-value would likely be greater than 0.10. This is because the sample mean (80.375) is not far from the claimed mean (83), and the sample size is small (8 scores), which typically results in a higher p-value indicating a weaker evidence against the null hypothesis (the professor's claim).
