An insurance company checks police records on 566 accidents selected at random and notes that teenagers were at the wheel in 83 of them. Complete parts a)
through d)
a) Construct the 95% confidence interval for the percentage of all auto accidents that involve teenage drivers
95% C ON)
(Round to one decimal place as needed)
b) Explain what your Interval means
OA We are 95% confident that the true percentage of accidents involving teenagers falls inside the confidence interval limits
OB. We are 95% confident that a randomly sampled accident would involve a teenager a percent of the time that fals inside the confidence interval limits
Oc We are 95% confident that the percent of accidents involving teenagers is 14.7%
) Explain what 95% confdence" means
About 95% of random samples of size 566 wil produce a true proportion that contain(a) the confidence interval of accidents involving teenagers.
4) Apolician urging tighter restrictions on drivers icenses isued to leens says, "In one of every five auto accidents, a teenager is behind the wheel" Does the
confidence interval contradict this staterment?
OA The confidence interval does not contradict the assertion of the politician The igure quoted by the politician is outside the interval.
O B. The confidence interval contradicts the assertion of the politician. The figure quoted by the politician is outside the interval.
