a group of 6 students was asked, \how many hours did you watch television last week?\ here are their responses. 11, 10, 14, 10, 7, 15 find the median and mean number of hours for these students. if necessary, round your answers to the nearest tenth. (a) median: hours (b) mean: hours

Answer

Explanation:

Step1: Arrange data in ascending order

7, 10, 10, 11, 14, 15

Step2: Calculate the median

Since there are 6 (an even - numbered) data points, the median is the average of the 3rd and 4th ordered values. Median=$\frac{10 + 11}{2}=10.5$

Step3: Calculate the mean

The mean $\bar{x}=\frac{7 + 10+10 + 11+14+15}{6}=\frac{67}{6}\approx11.2$

Answer:

(a) 10.5 hours (b) 11.2 hours
