question 26

Multiple Choice

Frequent food questionnaires (FFQs) are often given to large groups of people to obtain information on their dietary habits. Study participants are asked about the frequency with which they consume certain goods. Another method to obtain information on foods consumed is a food diary. People are asked to record every type of food and amount consumed for a few days. Food diaries are more difficult to obtain and response rates are lower than for FFQs. A study was conducted to see how well frequent food questionnaires predict food consumed based on food diaries. The regression of alcohol consumption FFQ on alcohol consumption food diary had an intercept of a = 2.96 and a slope of b = 0.67. The predicted number of drinks consumed in the food diary, if the FFQ states 5 drinks, is:

• A)6.31.
• B)0.67.
• C)2.96.
• D)5.
