Step-by-step explanation:
A company claims that its soup vending machines deliver exactly 8 ounces of soup to every customer.
This means that the null hypothesis is that the mean is exactly 8, that is:
You do not want the vending machines to deliver too much or too little soup.

Answer:
The relative frequency of the middle school students who watch soccer the most is 33.3%.
Step-by-step explanation:
We are given the table,
Grade Basketball Baseball Football Soccer Tennis Other Total
Elementary 51 18 26 32 4 6 137
Middle 50 24 44 34 7 18 177
High 42 17 58 36 11 24 188
Total 143 59 128 102 22 48 502
Now, we are required to find the relative frequency of the middle school students who watch soccer.
Since, we know,
Total number of students who watch soccer = 102
Number of middle school students who watch soccer = 34
Thus, the relative frequency of the middle school students = = 0.333 i.e. 33.3%
Hence, the relative frequency of the middle school students who watch soccer the most is 33.3%.
