An evaluation of a group of students was undertaken to analyze their student loan status. 1620 students were looked at. Of that groups, 899 did not require any loans to go to school. The mean scholarship amount received by this group (the group that did not require loans) was $3890. The remaining 721 students received an average scholarship amount of $4320. As a result, there was a $430 difference between the two groups which seems reasonably large. A scholarship committee suggests that this difference to state that they do a pretty good job of giving some additional scholarship assistance to students who have to take out loans. The standard deviation of this difference is given here: $340. (Note: This is the SD - not the standard error. So we do not have to divide by the square root of n.) Do a complete hypothesis test, demonstrating your understanding of each step. (You don't have to explain in extreme detail, just demonstrate your understanding of the steps involved). Use the standard value for alpha. Your answer should be done in the traditional ("older") hypothesis test format. That is, do not use the confidence interval method for this question. You will do so in a question below.
