The statistical discrepancy is equal to gross domestic product less gross domestic income. It means that Statistical discrepancy is the difference between demand and supply in na-tional accounts. Even though by defination the items should be equal in the national economy, they usuially deviate from one another due to deviation in statistical sources and they are not forced to be equal in the finnish systems of accounts.
In same way The test of significnce showed that the diffrence between the smple mean and the population mean is statistically significant.
Let us we take D(p1, p2); p1 is sample mean and p2 is population mean then difference between them measure they are differe or not. Like as if there is no difference then it is statistically unbiased and if there is diiference then they are statistically biased.

A quality control inspector is interested in comparing two concreting companies with respect to overall quality of their work. One measure of quality is whether or not the concrete that has been poured is at least 15 centimeters (cm) thick. The inspector has recorded details for jobs from both companies and is now interested in whether the companies differ with respect to this measure of quality. Let p1 denote the true proportion of times that Company 1 will fail to...
