For the following, indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variab
le 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 a______________a. qualitativeb. quantitativec. variable.
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."
Basketball is a type of sport that requires aggressive behavior and prolonged stamina. The height is a major advantage because he can sprint faster from between two sides of the court. Also, it would be much easier to shoot because he has a higher reach to the ring. This is also useful for steals and blocks. Basically, the height is a requirement because of longer limbs.
