Answer:
(a) 
(b) 
(c) Fail to reject 
Step-by-step explanation:
Given




Solving (a): The test statistic
This is calculated as:

So, we have:



--- approximated
Solving (b): Range of p value
First, calculate the degree of freedom (df)



Using:
--- significance level
The p value at:
is:

and the range is:


Solving (c): The conclusion
Compare the p value to the level of significance value
We have:


By comparison:

because:

<em>Hence, the conclusion is: fail to reject </em>
<em></em>

Answer:
The population of California is about 5 times the population of south Dakota
Step-by-step explanation:
Let
x ------> the population of California
y -----> the population of south Dakota
we have
x=4,000,000 people
y=800,000 people
Divide the population of California by the population of south Dakota, to find out how many times the population of South Dakota is the population of California
so
x/y
substitute
4,000,000/800,000=5
therefore
The population of California is about 5 times the population of south Dakota
