A sample of human brain volumes (cm3) is given below. Use the
given data values to identify the corresponding z scores that are
used for a normal quantile plot, then identify the coordinates of
each point in the normal quantile plot. Construct the normal
quantile plot, then determine whether the data appear to be from a
population with a normal distribution.

Given below is simple random sample data for wait times, in
minutes, for a call center. At the 98% confidence level, calculate
the confidence interval estimate for the variance in wait time for
the population of all calls at the call center. Assume the
population is normally distributed. 12.1 11.5 13.4 16.2 11.3 12.2

Given the values of So given below in J/mol K and the
values of ΔHfo given in kJ/mol, calculate the
value of ΔGo in kJ for the combustion of 1 mole of
propane to form carbon dioxide and gaseous water at 298 K.
S (C3H8(g)) = 274
S (O2(g)) = 209
