Answer:
The homoskedasticity-only F-statistic and the heteroskedasticity-robust F-statistic typically are different.
Step-by-step explanation:
An F statistic is a value derived by running an ANOVA test or a regression analysis to find out if the means between two populations are significantly different.
The homoskedasticity-only” F-statistic is derived by running two regressions, one under the null hypothesis and one under the alternative hypothesis. If the “unrestricted” model fits sufficiently better, reject the null.
In the first regression, the restricted regression (the null hypothesis) is forced to be true. This is the regression in which all the coefficients are set to zero; the relevant regressors are excluded from the regression. In the second regression, the unrestricted regression, the alternative hypothesis is allowed to be true. If the sum of squared residuals is sufficiently smaller in the unrestricted than the restricted regression, then the test rejects the null hypothesis
The heteroskedasticity-robust F-statistic is built in to STATA (“test” command); this tests all q restrictions at once.
The homoskedasticity-only F-statistic is important historically (and also in practice), and can help intuition, but isn’t valid when there is heteroskedasticity

Enter the number that belongs in the
green box.
Answer:
28
Step-by-step explanation:
35/5 ÷ -3/4
=7÷ (-3/4)
=7× (4/-3)
=(7×4)/-3
=- 28/3
the minus is already placed in the question, that makes the answer 28 without the minus
Leah’s family took a 3-hour trip in a car. They left at 10:30 am. What time did Leah’s family arrive?
Answer:

3(2y + 3) + y
Answer: 7y + 9
Step-by-step explanation: First you will distribute 3(2y + 3). This means we will multiply 3 to the numbers in the parenthesis. 3 x 2y = 6y and 3 x 3 = 9. This is 6y + 9.
Now we have the y left over so combine like terms 6y + y and that is 7y.
Answer:
7y + 9.
Step-by-step explanation:
1. Expand by distributing terms.
3(2y + 3) + y
2. Collect like terms.
(6y + y) + 9.
3. Simplify.
7y + 9.
Hope this helps.

Over the past several years, the owner of a boutique on Aspen Avenue has observed a pattern in the amount of revenue for the store. The revenue reaches a maximum of about $ 46000 in March and a minimum of about $ 28000 in September. Suppose the months are numbered 1 through 12, and write a function of the form ()=sin([−])+ f ( x ) = A sin ( B [ x − C ] ) + D that models the boutique's revenue during the year, where x corresponds to the month. If needed, you can enter π =3.1416... as 'pi' in your answer. ()= f ( x ) =
Answer:
F(x) = [tex]9000 sin (\frac{\pi }{3} (x-3) + 37000[/tex]
Step-by-step explanation:
Revenue reached in March = $46000 ( Maximum )
Revenue reached in September = $28000 ( Minimum )
f(x)=Asin(B[x−C])+D
attached below is the detailed solution of the problem

Answer: if your trying to simplify it....
−3xz+4x−7z+8 <----- this is your answer
if your trying to factor...
4x−3xz+8−7z <------ is your answer
if Finding the exact value using trigonometric identities.
−3xz+4x−7z+8 <---- is your Answer
I don't know where your going with this....
Step-by-step explanation:
Let's simplify step-by-step.
4x+xz+8−4xz−7z
=4x+xz+8+−4xz+−7z
Combine Like Terms:
=4x+xz+8+−4xz+−7z

minute card for $10.50 or a 300-minute card for $18.25. Which card is cheaper to buy per minute? (2pts) Write the
number of minutes card on the answer line.
Answer:eoeould say 18.25 because for 300 minutes only for 18.25 is cheap.And yes the other one is cheaper but for the money but its only 200.Tell me would YOU want only 200 instead of 300 because 300 costs a lot more than 18.25 so that person must be getting it on sale lol HOPE THIS HELPS AND IS RIGHT!!!!! ;)

A cafeteria sold 8 1/6 gallons of soda during lunchtime. 2 5/6 gallons were regular soda, and the rest was diet soda. How many gallons of diet soda were sold?
Write your answer as a fraction or as a whole or mixed number.
_________ gallons
Answer:
5 1/3 gallons
Step-by-step explanation:
Equation: 8 1/6 - 2 5/6
8-2=6
1/6-5/6= -4/6
6-4/6=5 2/6
Simplify:

bernie spends three hours a day on homework. if the spends 3/4 of an hour on science, 3/4 of an hour on social studies, and 1/4 of an hour on english, how much time does bernie spend on math
Answer:
Step-by-step explanation:
Math = 3 - Science - social studies - english
Math = 3 - 3/4 - 3/4 - 1/4
Math = 3 - 1 3/4
Math = 3 - 1.75
Math = 1.25 or 1 1/4

Find the length and width of a rectangle with maximum area that has a perimeter of 9P units.
Answer:
l = 9p/4 , l = 9p/4
Step-by-step explanation:
Given:
Perimeter = 9p
Find:
Length and width
Computation:
Assume;
Length = l
Perimeter = 2(l+b)
9p/2 = l+w
w = 9p/2 - l
Area = lb
Area = l(9p/2 - l)
Using differentiation
l = 9p/4
w = 9p/2 - l
w = 9p/2 - 9p/4
w = 9p/4
find the value of x
Answer:
141°
Step-by-step explanation:
The angle given is 39°;
Since this problem deals with angles in a transversal, it is easy to solve.
Now;
Angle given is a corresponding angle to the angle a;
Corresponding angles are equal; so angle a = 39°
Also,
angle a is corresponding to angle b;
angle b = 39°
So, angle b and x are on a straight line;
b + x = 180
x = 180 - 39 = 141°

The sum of three numbers is 97. The third number is 2 times the second. The second number is 9 less than the first. What are the numbers?
Answer:
The numbers are 26.5, 53 and 17.5.
Step-by-step explanation:
97=x+(x-9)+2x
97+9=4x
106/4=4x/4
x= 26.5
x-9 = 17.5
2x= 53
