Research always begin with a question about a group of sample.

U is a value that describe a sample. It derived from measurements of the indv in the sample. U?

M = 80, s = 10, z = 1.5. Find the X value.

Population use inferential statistics to answer questions about the sample.

For a sample with s = 12, X = 83, z = -0.25. Find mean for the sample. (without doing any cal.)
