The research question is focused on the amount respondents believe they will spend, which is a measure of central tendency (average). Therefore, using the "GENERALIZE" option is correct. Additionally, since we are interested in estimating the average amount respondents will spend, we should use the "AVERAGE" option. Finally, in order to estimate the range of values within which the true average lies with a certain level of confidence, we need to use "CONFIDENCE INTERVAL." Therefore, D (GENERALIZE; CONFIDENCE INTERVAL; AVERAGE) is the best choice.
