Question set 1: one instructor believes that students take more than 2 classes per quarter on average. he randomly interviewed a class of 24 students and found out the mean number of classes per quarter is 2.3 classes and standard deviation of 0.8. assume alpha is 0.05. (a) set up the hypothesis..

There is statistical evidence at 95% level to claim that students attend more than 2 classes per quarter

Step-by-step explanation:

Given that one instructor believes that students take more than 2 classes per quarter on average. Let X be the no of classes students take.

(Right tailed test at 5% significance level)

Mean difference =

Std error =

Test statistic t = mean diff/std error = 1.84

p value =0.039

Since p <0.05, we reject null hypothesis.

There is statistical evidence at 95% level to claim that students attend more than 2 classes per quarter

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
