Answer:
a) Z for northern region = 1 , Z for southern region = -1.2
b) Southern region
Step-by-step explanation:
a) Z = (x – mean)/standard deviation
Le x be weight for birds
For the northern region
Z = (13 – 10)/3
Z = 1
For the southern region
Z = (13 – 16)/2.5
Z = -1.2
b) to find in what region is more likely to find a bird with 13 ounces, we calculate the probability for each z value
For the northern region
P (x>13) = P(z > 1)
Then we use the z table to find the area under the curve.
P (x>13) = 0.1587
For the southern region
P (x>13) = P(z > 1.2)
Then we use the z table to find the area under the curve.
P (x>13) = 0.8849
Is it more likely that a bird with a weight greater than 13 ounces lives in the southern region
