When you do hypothesis testing, you have to first claim different hypotheses.

The first is called the NULL hypothesis

H0: The average of the data set is at least 415

Then you have an ALTERNATE hypothesis:

HA: the average of the data set is less then 415.

First step, you have to calculate the Average of the group:
add up all of the numbers, and then divide by the sample ...
