In a test of the quality of two television commercials, each commercial was shown in a separate test area six times over a one-week period. The following week a telephone survey was conducted to identify individuals who had seen the commercials. Those individuals were asked to state the primary message in the commercials. The following results were recorded.
| Commercial A | Commercial B | |
| Number Who Saw Commercial | 148 | 203 |
| Number Who Recalled Message | 62 | 62 |
What is the value of the test statistic (to 2 decimals)?
What is the p-value (to 4 decimals)?
Compute a 95% confidence interval for the difference between the recall proportions for the two populations (to 4 decimals).

commercials shown during daytime television (7am-5pm) and primetime
television (6pm-11pm), what do you think you would find? Why do you
think commercial content is different during these two times? If
you wanted to test your hypotheses, what would your unit of
analysis be? What would your units of observation be?

Feminized faces in TV commercials. Television commercials most
often employ females or “feminized” males to pitch a company’s
product. Research published in Nature (August 27 1998) revealed
that people are, in fact, more attracted to “feminized” faces,
regardless of gender. In one experiment, 50 human subjects viewed
both a Japanese female face and a Caucasian male face on a
computer. Using special computer graphics, each subject could morph
the faces (by making them more feminine or more masculine) until
they...

In a particular metro area, there are three commercial
television stations, each with its own news program from 6:00 to
6:30 pm. According to a report in this morning’s local newspaper, a

the news on WNAE (channel 5), 81 watched on WRRN (channel 11), and
67 watched on WSPD (channel 13). At the .02 significance
level, is there a difference in the proportion of viewers watching
