2. The University of Pennsylvania’s National Annenberg Election Survey of 2004 studied the
humor of late-night comedians Jon Stewart, Jay Leno, and David Letterman. Between July 15
and September 16, 2004, they performed a content analysis of the jokes made by Jon Stewart
during the “headlines” segment of The Daily Show and by Jay Leno and David Letterman during
the monologue segments of their shows. The data that they gathered was:
Leno: 315 of the 1313 jokes were of a political nature
Letterman: 136 of the 648 jokes were of a political nature
Stewart: 83 of the 252 jokes were of a political nature

a

Organize the data into a two-way table, with the explanatory variable as the columns and
the response variable as the rows.

b For each comedian, calculate the conditional proportion of his jokes that were political in
nature. Comment on what your analysis reveals.
c

State the null and alternative hypotheses in symbols, defining the symbols that you use.

d Would you analyze these data using a Chi-square Test or an ANOVA?

e

Also comment on whether you believe the technical conditions are met for this procedure
to be valid.

f

The test statistic is found to be 14.184 with p-value = .001. Sketch the null distribution, label
and scale the horizontal axis, and shade the area representing the p-value.
