Answer:
40
Step-by-step explanation:
The Interior of a triangle adds up to 180. 180 - 90 - 50 = 40
This means that the sample mean is not systematically smaller or larger than the population mean. Or put another way, if we were to repeatedly take lots and lots (actually an infinite number) of samples, the mean of the sample means would equal the population mean.
