According to the historical data, the life expectancy in
Argentina is equal to the life expectancy in Bolivia. A new study
has been made to see whether this has changed. Records of
240
individuals from Argentina who died recently are selected at
random. The
240
individuals lived an average of
74.6
years with a standard deviation of
4.6
years. Records of
250
individuals from Bolivia who died recently are selected at
random and independently. The
250
individuals lived an average...

Suppose we want to test whether or not three means are equal. We
want to perform this test with a 2% significance level.
If we perform an ANOVA test, what is the probability of
the test producing accurate results (avoiding a Type I
error)?
Suppose we, instead, run three separate hypothesis tests
(t-tests), each with 2% significance level.
Mean 1 = Mean 2
Mean 1 = Mean 3
Mean 2 = Mean 3

a) WHO is examining the improvement in life expectancy in an
underdeveloped country. Historical data for the population shows a
population mean life expectancy of 58.3 years, and with a
population standard deviation of 4.52 years. A recent sample of 75
people produced a sample mean of 60.8 years and a sample standard
deviation of 2.84 years. Evaluate H0: μ ≤ 58.3 and HA: μ > 58.3
at a .01 level of significance.

A group of researchers want to determine if there are any
significant differences in life expectancy between smokers and
nonsmokers. They test this question with a sample of 62 nonsmokers,
where the average life expectancy was 78 years (SS = 2200), and a
sample of 50 smokers, where the average life expectancy was 68
years (SS = 2300). Use a confidence interval (where α = .01) for
the appropriate statistical test to determine if there is a
significant difference in...

bad health and disability.
a bad economy.
bad health excluding disability.
death of a breadwinner in the family.
to disability excluding bad health.
