An insurance company finds that of 629 randomly selected autoaccidents, teenagers were driving the vehicle in 118 of them.

(a) Find the 95% confidence interval for the proportion of autoaccidents with teenaged drivers:
( , ) (Use 4 decimals.)

(b) What does this interval mean?

We are 95% confident that the proportion of all accidents withteenaged drivers is inside the above interval.

We are 95% confident that a randomly chosen accident with ateenaged driver will fall inside the aboveinterval.   

We are 95% confident that of the 629 sampled accidents, theproportion with a teenaged driver falls inside the aboveinterval.

We are 95% confident that the percent of accidents with teenageddrivers is 18.8%.

(c) What does the 95% confidence level mean?
We expect that 95% of random samples of size 629 willproduce  ---(A) a sample proportion (B) a true proportion(C) confidence intervals --- that contain(s) the  --- (A)sample proportion (B) confidence interval (C) true proportion ---of accidents that had teenaged drivers.

(d) A politician urging tighter restrictions on drivers' licensesissued to teens says, \"One of every five auto accidents has ateenaged driver.\" Does the confidence interval support orcontradict this statement?

The confidence interval supports the assertion of thepolitician. The figure quoted by the politician is inside theinterval.
