Question 1:

A school conducts a survey to understand the energy consumption of students' electronic devices. The survey results are presented in a table showing the number of students and the quantity of electronic devices they have at home. The table reveals that 10% of students have 1 device, 25% have 2 devices, 30% have 3 devices, and the rest have 4 or more devices. Based on this data, answer: 1) How many students were interviewed if the sample covered exactly 150 students? 2) If each electronic device consumes an average of 300 kWh per year, what is the estimate of the annual energy consumption of these students only with the electronic devices considered in the survey? Explain the reasoning used to arrive at these answers, taking into account the percentage distribution of students and the relationship with the number of electronic devices owned.
