STATS 401 REVIEW EXAM WITH COMPLETE SOLUTIONS!!
independent - ANSWER x does influence y
interpretation of standard deviation for one population - ANSWER approximate the
average distance of the possible p-hats for repeated samples of size n from the true
population proportion p
interpretation of standard error for one population - ANSWER estimating,
approximately, the average distance of possible values from the true population
proportion p
independent samples - ANSWER measurements in one sample not related to
measurements in other sample
two questions of interest for two populations - ANSWER 1) what is value of difference
between p-hats
2) test hypothesis is zero
interpretation of standard error for difference in sample proportions - ANSWER
standard error of p-hat one minus p-hat two estimates, roughly, the average distant of
possible p-hat one minus p-hat two values from p one minus p two
theta - ANSWER standard deviation of population
interpretation of standard deviation about one mean - ANSWER approximately the
average distance of possible sample mean values (for repeated samples of size n) from
the true population mean mu.
s - ANSWER standard deviation of sample
