Hartley and Ross (1954) derived the following exact bound on the relative size of the bias and standard error of a ratio estimate:

b. Apply the bound to Problem 43 using sample estimates in place of the given population parameters.

Reference

Suppose that for Example D in Section 7.3.3, the average number of occupants per condominium unit in the sample is 2.2 with a sample standard deviation of .7 and the sample correlation coefficient between the number of occupants and the number of motor vehicles is .85. Estimate the population ratio of the number of motor vehicles per occupant and its standard error. Find an approximate 95% confidence interval for the estimate.
