After surveying students at a college, a campus organization calculated that a 95% confidence interval for the mean cost of food for one term is ($1372, $1562). Now the organization is trying to write its report and is considering the following interpretations. Comment on each. Complete parts a through e below. Question content area bottom Part 1 a) 95% of all students pay between $1372 and $1562 for food. Comment on the given interpretation. Choose the correct answer below. A.
