Question

Six students from a statistics class reported the number of hours of television they watched per week. here are their data: 8, 10, 5, 14, 3, 6. what is the mean number of hours of television watched per week for this sample of six students? 8.00 5.50 7.00 7.67

Answer 1

To calculate the mean, you have to first take the sum of all the hours of television watch and then divide that number by the total number of students. In this example, the sum of hours would be: hours = 8+10+5+14+3+6 = 46 hours. Next, you know that the total number of students is 6. Finally, to calculate the mean, take the total number of hours and divide by number of students: 46 / 6 = 7.67 hours.
