At a certain Senior High School, a random sample of 10 students was taken and asked about their daily food expenditures prior to the COVID-19 pandemic. It was found that their average daily food expenditure is 195.34 pesos with a standard deviation of 60.56 pesos. A. If a 90% confidence interval is to be constructed for the population average daily food expenditure, what degrees of freedom must be used? [Select] B. Construct a 90% confidence interval for the population average daily food expenditure. [Select] C. Which of the following is the best interpretation of the result? [Select] Select] We are 90% confident that the sample average daily food expenditure is within the interval. We are 90% confident that the true average daily food expenditure, is between the lower limit and upper limit of the interval. There is a 90% chance that the true average daily food expenditure is within the interval. We are 90% confident that the true average daily food expenditure is 195.34 pesos.
