A random sample of 500 registered voters in Phoenix is
asked if they favor the use of
oxygenated fuels throughout the year to reduce pollution. If more
than 315 voters
respond positively, we conclude that at least 60% of the voters
favor the use of these
fuels.
a) Find the type I error probability if exactly 60% of the voters
favor the use of
these fuels.
b) What is the probability of error type II β if 75% of the...

From a random sample of potential voters in an upcoming
election, 47% indicated they intended to vote for Candidate R. A 95
percent confidence interval was constructed from the sample and the
margin of error for the estimate of 5%. Which of the following is
the best interpretation of the interval?
A) We are 95% confident that the proportion who intend to vote
for Candidate R from the random sample is between 42% and 52%
B) We are 95% confident...

Would you favor spending more federal tax money on the arts? Of
a random sample of n1 = 94 politically
conservative voters, r1 = 17 responded yes.
Another random sample of n2 = 84 politically
moderate voters showed that r2 = 22 responded
yes. Does this information indicate that the population proportion
of conservative voters inclined to spend more federal tax money on
funding the arts is less than the proportion of moderate voters so
inclined? Use α = 0.05....
