Use the following to answer the questions below:

In a survey conducted by the Gallup organization, 1,017 adults were asked "In general, how much trust and confidence do you have in the mass media — such as newspapers, TV, and radio — when it comes to reporting the news fully, accurately, and fairly?" The results are summarized in the provided table.

ResponseCount
"Great deal" of confidence81
"Fair amount" of confidence325
"Not very much" confidence397
"No confidence at all"214
We are interested in testing whether or not the four responses are equally likely.


Which opinion has the largest contribution to the chi-square test statistic? For this age group, is the observed count smaller or larger than the expected count?
