Answer:

The claimed proportion (population) is

p=0.11

The sample proportion (p-hat) is

\hat{p}=0.10

Step-by-step explanation:

In the population, we have the parameter p that is 11%.

p=0.11

Then, a sample of n=160 is taken and the proportion of the sample is 0.10.

\hat{p}=0.10

The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.

Step-by-step explanation:

1/4 equals 0.25 gallons, 1/2 gallons is 0.5, so Will will have a mix of 0.75 gallons. If each serving is 1/16 and 1/16 equals 0.0625, divide 0.75 by 0.0625 = 12 servings.
