Answer:
-0.5
Step-by-step explanation:
σM=σ/√N
=9/√36
=9/6
=3/2=1.5
Z=(x-μ)/σ/√N
=(19.5-24)/9/√36
=-4.5/1.5=-3
The probability that the sample mean will be larger than 19.5 = -0.5
P(>19.5)=P(Z>-3)= -0.5
Let, the weight before 3 years = x
Then, it would be: x * 150/100 = 45
x * 1.5 = 45
x = 45/1.5
x = 30
So, your final answer is 30 Pounds
Hope this helps!
