Problem:

On the planet Sidue, the color of Groton Wheat is a quantitative trait. A random sample of 10 stalks taken from different planets yields the following measurements (in Groton Wheat Units (GWU)): 34, 6, 18, 65, 2, 3, 11, 18, 19, 35.

Usually, values that are more than 2 standard deviations away from the mean (in either + or - direction) are considered "unlikely" and require additional inspection.

Required:

Question: How many such measurements satisfy that condition?

Show your calculations, but you do not need to write out any explanation.
