Last year, a soft drink manufacturer had 21% of the market. In order to increase their portion of the market, the manufacturer has introduced a new flavor in their soft drinks. A sample of 400 individuals participated in the taste test and 100 indicated that they like the taste. We are interested in determining if more than 21% of the population will like the new soft drink at the significance level 0.05.

The p-value is best interpreted as the following:

a. The p-value indicates the probability of observing the proportion of people who like new flavor equal to 25% or lower in the sample of 400 individuals, if actual proportion of people who like the new flavor is 21%.

b. The p-value indicates the probability of observing the proportion of people who like new flavor equal to 25% or greater in the sample of 400 individuals, if actual proportion of people who like the new flavor is 21%.

c. The p-value indicates the probability of observing the proportion of people who like new flavor equal to 21% or greater in the sample of 400 individuals, if actual proportion of people who like the new flavor is 21%.
