Suppose that, according to a recent census, the income per capita measured in U.S. dollars was $42 comma 793 in country A and $46 comma 210 in country B. Assume that income per capita is Normally distributed with a standard deviation equal to 29% of the mean for each country. A random sample of eight people in country A and eight people in country B is selected.
a) What is the probability that the mean income of the sample from country A is above $46 comma 210?
b) What is the probability that the mean income of the sample from country B is above $42 comma 793?
c) What would be the effect of not assuming that the income per capita is Normally distributed?

According to the U.S. Census Bureau, the mean per capita income
in Texas is $25840, whereas the mean per capita income in Florida
is $26560. Suppose both distributions are normal, each with a
standard deviation of $8000. Suppose the samples of 100 residents
of each state are taken.
Find the probability that the sample mean per capita income in
Texas will exceed $27600.
