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 ...
The solution uses the data set below to test the claim that more than 50% of the are at least 415.
