- A businesswoman is planning to have a restaurant in the university belt. She wants to study the weekly food allowance of the students in order to plan her pricing strategy for the different menus she is going to offer. She asked 213 students and gathered the following data: 1. What is the average of the given data? 2. What is the mode of the given data? 3. Determine the weekly food allowance where 60% of the students have at most. 4. What percentage of the students have a weekly food allowance that is at most 170 pesos? 5. If the businesswoman wanted to have at least 50% of the students could afford to eat in her restaurant, what should be the minimum total cost of the meals that the student could have in a week?The interaction plots and means table are provided below.
