I hope this helps.

Answer:

76.

Step-by-step explanation:

We have been given the results of a survey that shows the percentage of preferred TV channel by 400 people to watch the evening news.

To find the number of people who preferred WWCN than WANR, we will subtract the number of people watched WANR from the people, who watch WWCN.

Since 41% of 400 prefer WWCN and 22% of 400 prefer WANR, so 19% (41%-22%) of 400 will prefer WWCN than WWNR.

\(\text{Number of people who preferred WWCN than WANR}=\frac{19}{100}*400\)

\(\text{Number of people who preferred WWCN than WANR}=0.19*400\)

\(\text{Number of people who preferred WWCN than WANR}=76\)

Therefore, 76 people preferred WWCN than WANR.
