It has been found in previous studies that 71% of all teenage marriages end in divorce. In order to test this statistic, a sample of 87 couples married as teenagers were followed for twenty-five years to determine if they stayed married or not. Out of the 87 couples surveyed, 68 ended in divorce. At the .05 los, can we conclude that more than 71% of teenage marriages end in divorce? 3 pts for (a) – (e)

It has been found in previous studies that 70% of all teenage
smokers end up quitting. In order to test this statistic, a sample
of 87 teenage smoker were followed for twenty-five years to
determine if they continued smoking or not. Out of the 87 teenagers
surveyed, 68 ended up quitting. At the .05 los, can we conclude
that more than 70% of teenage smokers ended up quitting?

The overall divorce rate (i.e., the number of divorces divided
by the number of marriages) has fallen dramatically since the
1980s. Since the rate is calculated relative to the number of
marriages, this cannot be chalked up to fewer marriages. People who
get married today have a much higher likelihood of staying married
relative to thirty years ago. How might you use our economic
principles to explain this result? Explain.

From previous studies, it has been generally believed
that Northern Hemisphere icebergs have a mean depth of 270 meters.
An environmentalist has suggested that global warming has caused
icebergs to have greater depth. A team of scientists visiting the
Northern Hemisphere observed a random sample of 41 icebergs. The
depth of the base of the iceberg below the surface was carefully
measured for each. The sample mean and standard deviation were
calculated to be 276 meters and 20 meters respectively....

Previous studies suggest that the length of time that a FL
resident has resided in the city is normally distributed with a
population standard deviation of 11.95 months.
a) In order to construct a 94% confidence interval for the true
mean time with a margin of error no greater than 2
months, how large of a sample should be
gathered?
The critical value, zc= (round to two
decimal places).
The sample size, n = .
b) A random sample of 203 FL...
