Deer mice are small rodents native of North America. Their adult body lengths (excluding tail) are known to vary approximately Normally, with mean μ = 83 millimeters (mm) and standard deviation σ = 7 mm. A researcher uses a random sample of 25 deer mice.

Determine what 10% of the 25 deer mice will have mean millimeter body length less than:
