Answer:
The distribution will be approximately normal, with mean 350,000 and standard deviation 25,298.
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.
Population:
Suppose the selling price of homes is skewed right with a mean of 350,000 and a standard deviation of 160000
Sample of 40
Shape approximately normal
Mean 350000
Standard deviation 
The distribution will be approximately normal, with mean 350,000 and standard deviation 25,298.
Answer: <DEF & <JKL
Step-by-step explanation:
they equal 90 degrees
complementary angles equal 90 degrees
Step-by-step explanation:
4x+x-1+2x+1
since any number power zero is one
group like terms
4x +x+ 2x-1+1
7x=0
divide both sides by 7
x= 0
