Answer:
(a/b)^3 times 2/(b^4)
or
2(a/b)^3times 1/(b^4)
or instead of 1/b^4 ------>b^-4
Step-by-step explanation:
Answer:
(a) Null Hypothesis (H₀) = Mean of x₁ > Mean of x₂
Alternative Hypothesis (H₁) = Mean of x₁ ≠ Mean of x₂
(b) We will use here t-test for two sample means which is given by,
![[tex]t = \frac{\bar_{x_{1}}-\bar_{x_{2}}}{\sqrt{s^2(\frac{1}{n_{1}}+\frac{1}{n_{2}} )}}](https://tex.z-dn.net/?f=%5Btex%5Dt%20%3D%20%5Cfrac%7B%5Cbar_%7Bx_%7B1%7D%7D-%5Cbar_%7Bx_%7B2%7D%7D%7D%7B%5Csqrt%7Bs%5E2%28%5Cfrac%7B1%7D%7Bn_%7B1%7D%7D%2B%5Cfrac%7B1%7D%7Bn_%7B2%7D%7D%20%20%29%7D%7D)
[/tex]
Putting all values we get, t = 17.5 with 20 degree of freedom
At α = 0.05
p-value = 95% Confidence Interval for the Difference ( 6.6068 , 8.3932 )
Answer:Temperature of 10 degrees
Step-by-step explanation:
The others involve a decrease of 10 units, justifying use of a megative number.
He should first multiply both sides by 8, to get rid of the denominator.
5/8 m = 25
8(5/8 m) = 8(25)
5m = 200
He should then divide both sides by 5, to get rid of the coefficient
5m/5 = 200/5
m = 40
So m = 40 by these steps
I believe 150,000. You're welcome ;-)
