Given : Green sea turtles have normally distributed weights, measured in kilograms, with a mean of 134.5 and a variance of 49.0
To Find : A particular green sea turtle's weight has a z-score of -2.4
What is the weight of this green sea turtle
Solution:
Z score = (Value - Mean) /SD
Mean = 134.5
SD = √Variance
=> SD = √49
=> SD = 7
z = -2.4
=> -2.4 = ( Value - 134.5)/7
=> -16.8 = Value - 134.5
=> Value = 134.5 - 16.8
=> Value = 117.7
=> Value = 118
weight of this green sea turtle Round to the nearesi whole number = 118 kg
