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.

1.What is the mean of sampling distribution in millimeters?

2.What is the standard deviation of the sampling distribution in millimeters?

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

3.What is the approximate probability that the sample mean body length would be less than 80mm?

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