It has become more common for shoppers to "comparison shop" using the Internet. Respondents to a survey in 2013 who owned cell phones were asked whether they had, in the past 30 days, looked up the price of a product while they were in a store to see if they could get a better price somewhere else. Here is a table of their responses by income level. Complete parts a) and b) below.

_	<$30K	$30K-$49.9K	$50K-$74.9K	>$75K
Yes	209	114	104	178
No	698	367	267	397
