Draw a random sample of 10 four- figure numbers starting from 1550 to 8000.

Explain in detail about sampling error.

A sample of 1000 students whose mean weight is 119 lbs(pounds) from a school in Tamil Nadu State was taken and their average weight was found to be 120 lbs with a standard deviation of 30 lbs. Calculate standard error of mean.

Explain the procedures of testing of hypothesis
