Question

A growing number of people have stopped paying for cable and satellite TV service, and don't even use an antenna to get free signals over the air. They are watching shows and movies on the Internet, sometimes via cellphone connections. Recently the Nielsen Co. started labeling people in this group "Zero TV" households, because they fall outside the traditional definition of a TV home.

Are younger people more likely to go "ZeroTV"? Compare the average age of the head-of household for "ZeroTV" homes and does who have TVs. In this problem, we want to make inferences about:

A) mean of matched pairs differences

B) difference of two independent means

C) difference of two independent proportions

D) one population proportion (I PUT THIS ANSWER AND IT WAS WRONG)

E) one population mean

Explanation / Answer

B option as two population.samples are independent, one from Zero TV and one from those who have TVs.

The Independent Samples t Test compares the means of two independent groups in order to determine whether there is statistical evidence that the associated population means are significantly different. The Independent Samples t Test is aparametric test. This test is also known as: Independent t Test.
