How unusual is that?

Population The goal is to describe this as accurately as possible.

Population Sample You take a sample.

Population µ Sample _ X _ You describe the sample.

Sample _ C XC Sample _ D XD Population Sample _ B µ Sample _ E XE XB Sample _ A XA The sample mean is just one of many possible sample means drawn from the population, and is rarely equal to the real population value.

Regression

_ Xboys=53. 75 _ Xgirls=51. 16 How do we know if the difference between these means, of 53. 75 - 51. 16 = 2. 59, is reliably different from zero?
