Part 1 of 4
A study is done to determine which of two soft drinks has more sugar. There are 25 cans of
Beverage A in the researchers' sample and 15 cans of Beverage B. The mean amount of sugar in
Beverage A is 34.7 grams per can with a sample standard deviation of 0.7 grams. The mean amount
of sugar in Beverage B is 33.9 grams with a standard deviation of 0.6 grams. The researchers believe
that Beverage A has less sugar than Beverage B, on average. Both populations are normally
distributed. Conduct a hypothesis test using a 2% level of significance.
