Answer:
A. The first equation is for sample data; the second equation is for a population.
Step-by-step explanation:
The first equation is y = 
, this is the equation for sample data as the intercept (
) and the slope parameter(
) both are calculated then we have got this and these values are not taken as given.
The Second equation is 
, this is the equation for population data as we can't calculate these 
and 
as we take these values as given and also we do testing for 
parameter using t test and it is sure that testing is always done on population data not on sample data.
Answer:
11 units
Step-by-step explanation:
<em>hey there,</em>

< A square has 4 sides that are all always equal to each other. The perimeter is all the sides summed up together. That means (for example), if one side of the square is 2 cm, then we know that the perimeter is 8 cm, because 2 + 2 + 2 + 2 = 8 (or 2×4=8).
Here we are given that one side is equal to "x-5". Pretend that is a number and solve as I did just right above:
(x-5)×4 = 4x -20
Now we know that the perimeter is (4x-20) units (when you don't know what the units are then just put "units").
We also know that the perimeter can be a number which is 24. That means these two values are equal to each other.
4x-20 = 24
Now solve! Bring x to one side, and all the numbers to the other side.
4x = 44
x = 11
We now know that the value of one side of the square (x) is equal to 11 units. >

Answer:
Total FUTA : $669.6
Step-by-step explanation:
Given the information
- Person 1 earned $3900 in the first quarter
- Person 2 earned $20100 in the first quarter
- Person 3 earned $6900 in the first quarter
As we know, FUTA is short for Federal Unemployment Tax Act, and the FUTA tax rate is 6.2% applied to a maximum cumulative earnings of $7,000.
So in this situation, only person 1 and 2 must pay FUTA tax because ther earning are lower than $7,000.
- Person 1: 3900 x 6.2% = $241.8
- Person 3: 6,900 x 6.2% = $427.8
=> Total FUTA : $669.6
