A researcher conducts a hypothesis test where he compares the scores of a random sample of students' SAT scores to the national average of 500. He hopes to show that the students' mean score will be higher than average. After conducting his experiment, he finds a p-value for his sample to be .06. What does this mean in the context of his experiment?

Group of answer choices

His students' mean score does not significantly differ from the national average, because his p-value is less than alpha.

His students' mean score does not significantly differ from the national average, because his p-value is greater than alpha.

His students' mean score does significantly differ from the national average, because his p-value is less than alpha.

2. A psychologist has developed a personality test on which scores can range from 0 to 200.  The mean score of well-adjusted people is 100.  It is assumed that the less well-adjusted an individual is, the more the individual’s score will differ from the mean value.  The Dean of Students at XYZ University is interested in discovering whether the students at XYZ are well-adjusted, on average. Fifteen students are randomly sampled. Their scores are:  80, 60, 120, 140, 200, 70, 30, 180, 70, 150,...
