A simple random sample of
26
filtered 100-mm cigarettes is obtained from a normally distributed population, and the tar content of each cigarette is measured. The sample has a standard deviation of
0.16
mg. Use a
0.05
significance level to test the claim that the tar content of filtered 100-mm cigarettes has a standard deviation different from
0.20
mg, which is the standard deviation for unfiltered king-size cigarettes. Complete parts (a) through (d) below.

A research conducted by the University of Michigan claimed that
there are more female drivers in the USA than male drivers. A
researcher decides to test this claim on his state. In his simple
random sample of 900 observations, he noticed that 468 of 900 were
women. At a = 0.05, is there enough evidence to support the
claim?

Suppose the amount of tar in cigarettes is normally distributed with mean 3.5 mg and standard deviation 0.5 mg. a.) What proportion of cigarettes have a tar content exceeding 4.25 mg? b.) "Low tar" cigarettes must have tar content below the 25th percentile of the tar content distribution. What is the value, which is the 25th percentile of the tar content distribution?

Refer to data table below, which shows the amounts of nicotine (mg per cigarette) in king size, 100 mm menthol, and 100 mm nonmenthol cigarettes. The king size cigarettes are nonfiltered, while the 100 mm menthol and the 100 mm nonmenthol cigarettes are filtered. Use a 0.05 significance level to test the claim that the three categories of cigarettes yield the same mean amount of nicotine. Given that only the king size cigarettes are not filtered, do the filters appear...
