Students in a seventh-grade class were given an exam. During the next 2 years, the same students were retested several times. The average score g can be approximated by the model

g(t) = 81 − 13 log₁₀(t + 1), 0 ≤ t ≤ 24

where t is the time (in months).

(a) What was the average score on the original exam? ???

(b) What was the average score after 6 months? (Round your answer to one decimal place.) ???

(c) When did the average score drop below 70? (Round your answer to the nearest month.)

The average score dropped below 70 after ??? months.

Suppose many classes took the same psychology exam and the average individual grade on the psychology exam is 70% (with a standard deviation of 10.4%). How much less likely is it to find a class (n=17) with an average on the psychology exam to be 75% than a single person with an average of 75% on the psychology exam?
