Following data relates to density of population, number of deaths and population of various cities. Calculate death rate and Karl pearson coefficient between density of population and death rate.

Cities = P, Q, R, S, T, U

Density of population = 200, 500, 700, 500, 600, 900

No. of deaths = 840, 300, 312, 560, 1440, 1224

Population = 42000, 30000, 24000, 40000, 90000, 72000

Death rate =No. of deaths/population x 100

After finding the death rates in each city you can find the karl pearson coefficient of correlation using the usual method.
