Answer 1

$1.a.~Experimental~unit:~People\\ Variable:~favorite~type~of~TV~program\\ It~is~qualitative~measure.\\ b.$

From the above diagram it is observed that the most favorite TV program is Comedy. Then people like to see Action program. But less people like to see Science fiction program.

c.

This is a nominal data. So we only compute frequency distribution and mode. Hence it is not possible to describe data in terms of skewness.

d.

The proportion of people prefer drama or comedy=(54+25)/150=0.5267
