twenty students were surveyed to find out how many hours of tv they watch during a school week. the results are shown to the right. answer the following questions and round your answers to the nearest half hour. the mean of the data is hours.

Answer

Explanation:

Step1: Calculate sum of hours

$2 + 5+3 + 5+1 + 4+6+12+2+6+4+1+2+6+2+3+10+10+8+7=96$

Step2: Calculate the mean

The number of students $n = 20$. Mean $\bar{x}=\frac{\text{Sum of hours}}{n}=\frac{96}{20}=4.8\approx5$ (rounded to nearest half - hour)

Answer:

$5$
