QUESTION 4 Forty five states of the united states (excluding the five largest) were arranged in nine strata with five states each, states in the same stratum having roughly the same ratio of 1950 to 1940 population. A stratified random sample with n, 2 gave the following results for 1960 population (y) and 1950 population (x) in millions stratum 5 4.67 3.93 3.96 3.44 6 4.32 .96 .41 1.33 7 4.56 4.06 3.57 3.29 9 2.18 1.9 1.75 0.23 0.13 4.95 2.78 0.97 0.91 0.61 0.53 .79 1.91 1.86 2.01 0.63 0.5 2.85 2.38 2.54 2.01 6.07 4.84 Yi Given that the 1950 population total is 97.94, estimate the 1960 population by the combined ratio estimate. Find the standard error of your estimate
