a. The labels on U-Turn protein energy bars include the statement that these bars contain “125% less fat than the leading chocolate candy brands” (based on data from Consumer Reports magazine). What is wrong with that claim?

b. In a Pew Research Center poll on driving, 58% of the 1182 respondents said that they like to drive. What is the actual number of respondents who said that they like to drive?

c. In a Pew Research Center poll on driving, 331 of the 1182 respondents said that driving is a chore. What percentage of respondents said that driving is a chore?

Step-by-Step Solution:

Step 1 of 1

a. If “100% less fat” was advertised, then there would be no fat. But 125% is not possible.

b. In a Pew Research Center poll on driving, 58% of the 1182 respondents said that they like to drive. The actual number of respondents who said that they like to drive is

58% 1182 = 685.56686.

c. In a Pew Research Center poll on driving, 331 of the 1182 respondents said that driving is a chore.

= 0.28

0.28100 = 28%

Therefore, 28% percentage of respondents said that driving is a chore.
