the Australian Stock Exchange.
What are the measures of variability?
b. Which ones (at least three) would you choose to use to analyse the central values in this
set of data? Explain why.
c. What are the values of the mean and standard deviation of the P/E ratio and dividend
yield?

3. An infinite population has a mean of 120 and a standard deviation of 44. A sample of 100
observations is to be selected at random from the population.
a. What is the expected value of the sample mean?
b. What is the standard deviation of the sample mean?
c. What is the shape of the sampling distribution of the sample mean?
d. What does the sampling distribution of the sample mean show?
A researcher conducted a survey on a university campus for a sample of 64 third-year
students. In the past it was reported that third-year students read an average of 3.12 books in
the prior academic semester, with a standard deviation of 2.15 books. Determine the
probability that the sample mean is:
e. less than 3.45.
f. between 3.38 and 3.58.
g. above 2.94.
