Answer:
That one of the pets center cost alot more
Step-by-step explanation:
Answer: We reject the null hypothesis and conclude that the treatment group has errors that vary significantly more than the errors of the placebo group.
Step-by-step explanation:
Null hypothesis : Var1 = Var 2
Alternative hypothesis : Var1 > Var 2
The F test statistic is the ratio of squared sample standard deviation:
F= (2.4)^2 / (0.75)^2 = 5,76/ 0,5625 = 10.24
Now we have to get the critical from the F table with degrees of freedom ( n1-1,n2-1)=(23,23) :
From the F table ,F(0.05) = between 2.0050 and 2.0476 .
General rule : if the value of the test statistic is in a rejection region . Reject We reject the Null hypothesis .
F= 10.24 > 2.0476 . Therefore we reject the null hypothesis .
Conclusion: The errors of the treatment group vary more than the error of the placebo group .
6/10 rounding to the nearest half would be 1, not 0.
Reason for this: Here is a number line to help you!
|----|----|
Left line = 0
Middle line = 1/2
Right line = 1
Here is another rule!
0/10, 1/10, 2/10, 3/10, 4/10 = rounded to the nearest half would be 0
5/10, 6/10, 7/10, 8/10, 9/10, 10/10 = rounded to the nearest half would be 1.
So 6/10 rounded to the nearest half is 1.
Hope this helped!

We know that
[volume of a cube]=b³
where
b------> is a side length of a cube
for b=5 in
[volume of a cube]=5³--------> 125 in³
the answer is 125 in³
