Answer:
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For proportions, the mean is 
and the standard deviation is 
In this problem, we have that:
.
So
The mean of the sampling distribution of the sample proportions is 0.82 and the standard deviation is 0.0256.
Answer:
K=8
Step-by-step explanation:
The triangles are similar so you can set up the porpotions: 3/6=4/k then you cross multiply and solve for k

Answer:
50 million
Step-by-step explanation:
current value: c
initial value : i
c = 1.2 × i
x - i = 10
10 + i = 1.2 × i
0.2 ×i = 10
i = 50
2x2x3=12 12x8=96 so the bale of hay weighs 96 pounds.
