Lady_Fox [76]

Answer:

  (1)  -5

kirill [66]

Answer:

The z-score of a beetle with a length of 2.38 centimeters is 2.4

z = (x - µ)/σ

x is the length of the beetle species.

µ is the mean length

σ is the standard deviation

Substituting the given values in above equation, we get

 

z = (2.38 - 1.9)/0.2

z = 0.48/0.2

z = 2.4
