For the following, indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variable of interest. Justify your response. Does chewing your food for a longer period of time reduce one's caloric intake of food at dinner? A researcher requires a sample of 75 healthy males to chew their food twice as long as they normally do. The researcher then records the calorie consumption at dinner. The confidence interval for a
should be constructed because the variable of interest isa. an individual's opinion, b. the number of individuals surveyed, c. an individual's chewing time, d. an individual's reduction in caloric intake,

which is aa. qualitativeb. quantitativec. variable.

Step-by-step explanation:

The research question is given as "Does chewing your food for a longer period of time reduce one's caloric intake of food atdinner?"

Here interest of study variable is "reduction of caloric intake of food at dinner".

For construction of confidence interval, the researcher records the calorie consumption at dinner.

Since calorie consumption is a variable, we need to construct confidence interval for mean.

So correct choice of sentences as "The confidence interval for a mean should be constructed because the variable of interest is an individual's reduction in caloric intake, which is a quantitative variable."
