Answer:
d. 200 and 2
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.
In this problem, we have that:
Mean = 200
Standard deviation = 18
Sample size: 81
Standard error:
So the correct answer is:
d. 200 and 2
$ 2772 is paid in state income tax
<em><u>Solution:</u></em>
Given that, Tina lives in a state that charges her 4.5% state income tax on her federal taxable income
Federal taxable income = $61,600
<em><u>To find: Amount paid by Tina in state income tax</u></em>
Tax rate = 4.5 %
<em><u>Which means, 4.5 % of $61,600 is paid as tax</u></em>
Here, "of" means multiplication or product
Thus $ 2772 is paid in state income tax
