Answer:
a) 151lb.
b) 6.25 lb
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size can be approximated to a normal distribution with mean and standard deviation .
In this problem, we have that:
So
a) The expected value of the sample mean of the weights is 151 lb.
(b) What is the standard deviation of the sampling distribution of the sample mean weight?
This is
<span>3/8 ÷ 0.5 = 3/4
2.5 ÷ 18/8 = 2/5
Since 3/4 > 2/5, he has too much milk. He'll get runny pancakes.Hope this helps! =)</span>
0.5b+2=3
0.5b=3-2
0.5b=1
b=2
