Given information
Use the following information to answer the next three exercises: A study is done to determine which of two soft drinks has more sugar. There are 
cans of Beverage A in a sample and six cans of Beverage B. The mean amount of sugar in Beverage A is 
grams with a standard deviation of 
grams. The mean amount of sugar in Beverage B is 
grams with a standard deviation of 
grams. The researchers believe that Beverage B has more sugar than Beverage A, on average both populations have normal distributions.
Step-by-step explanation
The random variable is the difference in sugar content between Beverage A and Beverage B, which is the average sugar content of the 
soft drinks.
Therefore,
If 
The mean amount of sugar in Beverage A and
The mean amount of sugar in Beverage B.
Then,
The random variable is,
