Explanation / Answer

(a) Here the last qualification shows "more than 12" number of hours which cannot be quanitified so mean cannot be calculated.

(b) As the total sample size is 1324. The half value is 662 so the cumulative frequency of 662 and 663 falls in between those group. that will be the medium group.

so the median value falls between 1 and 2.

(c) the median value is

The median value would be = (662.5 - 360)/(714 - 360) * (2 - 1) + 1 =  1.8545

(d) The median number of watchinf TV hours is not 6 as distribution of frequency is not symmetric.

(e) Here the shape is rightly skewed.

(f) Here as the distribution if rightly skewed the mean would be on the right of the median.
