A statistical hypothesis test to determine if there is enough evidence to reject the null hypothesis.

The initial assumption about the population parameter. In this case, it's that the mean cereal weight is 13 ounces.

The alternative hypothesis is the statement that we're trying to prove. In this case, it's that the mean cereal weight is different from 13 ounces.

A cereal manufacturer is concerned about the accuracy of cereal box filling weights.
Each box should contain 13 ounces of cereal.
A sample of 31 boxes was randomly selected.
The average weight of the sample is 12.58 ounces.
The standard deviation of the sample is 0.25 ounces.
A confidence interval needs to be calculated to test if the mean weight differs significantly from 13 ounces, at a significance level of 0.10.
Interpretation of the calculated confidence interval is required.
