The results were the following (in ounces): 15.5 16.2 16.1 15.8 15.6 16.0 15.8 15.9 16.2 Assume the weight of cereal in a box is normally distributed. Some customers believe that the variance of the weight of boxes with captain crisp cereal is more than 0.05. Use a = 0.10 to test the customers' claim.. Enter the test statistic in the first box and your decision in the second box ( 0 if you reject and 1 if you don't (i.e. if you accept)

Explanation / Answer

The statistical software output for this problem is:

One sample variance hypothesis test:
2 : Variance of variable
H0 : 2 = 0.05
HA : 2 0.05

Hypothesis test results:

Hence,

Test statistic = 10

Do not reject Ho.

In first blank: 10

In second blank: 1
