The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation and n is the size of the sample.
In this problem, we have that:
Then
The value of the test statistic is
The boxes from left to right are
100
2
25/3
The ratio is 5/3 pies to cakes so
Top square = bottom square times 5/3
OR
Bottom square = top square times 3/5
32,767/32,768 is in lowest terms and can't be reduced.
