For all problems below, use correct notation where
appropriate.
Round all proportions to 3 d.p. and standard errors to 4 d.p.
1. (up to 5 EC pts) Do we dream in color? In the 1940s, before the
age of television,
color movies, and video games, 29% of the American population
reported dreaming in
color. A psychologist suspects that the present-day proportion
might be higher, now
that we are surrounded with color imagery. In a random sample of
113 people, 92
reported dreaming in color (Schwitzgebel 2003).
a) State the parameter to be tested. Be specific and use the
appropriate notation.
b) Conduct a hypothesis test to determine if the psychologist’s
suspicion is
correct. Clearly show all 7 steps as shown in the lecture notes.
Complete each
step by hand. Be sure to state the hypotheses in words and
symbols.
c) In the context of this problem, what would it mean if we made a
Type I error?
What is the probability of making this kind of error? (See 8.1,8.2
lecture notes.)
