Ap statistics question? (this was on a quiz i had last week, and i'm really confused on how to do it.)

a teacher is wondering if 1st period students tend to do better on tests than 2nd period students. she takes a random sample of 5 1st period students whose scores were 98, 86, 75, 92, and 90. she takes a random sample of 3 2nd period students whose scores were 91, 89, and 87.

suppose that the original distributions of scores are normally distributed. do these data give evidence that the 1st period students do better?

perform the appropriate hypothesis test. show all work.

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
