Cola makers test new recipes for loss of sweetness during storage. Trained tasters rate the sweetness before and after
storage. Here are the sweetness losses (sweetness before storage minus sweetness after storage) found by 10 tasters
for one new cola recipe:
2.0,0.4,0.7, 2.0-0.4 2.2-1.3 1.2 1.12.3
Are these data good evidence that the cola lost sweetness? Use the four-step process and use a significance level of
5%. Assume the data is taken from a normal distribution.
