Q1.
Just as human height is approximately
normally distributed, we can expect the
heights of animals of any particular
species to be normally distributed.
Suppose that, for the past five years, a
zoologist has been involved in an
extensive research-project regarding the
animals of one particular species. Based
on his research-experience, He selects a
random sample of ten animals of the
particular species, and, upon measuring
their height the following data is
obtained.
63, 63, 66, 67, 68, 69, 70, 70, 71, 71.
Calculate a 90% confidence interval for
the mean of the population, supposed
normal, from which these data were
