The null hypothesis in the Durbin-Watson test is always that there is a. negative autocorrelation. b. no autocorrelation. c. eit

Kamila [148]

Answer:

b. no autocorrelation.

Step-by-step explanation:

The Durbin-Watson test assumes that

H0:ρ=0

HA:ρ≠0

p=0 is a statement for the null hypothesis that assumes that the error term in one period is not correlated to the error term in the previous period.

The Durbin-Watson test is used in regression analysis to test for autocorrelation. The results from the test would always range from 0 to 4. A value of less than 2.0 indicates positive autocorrelation. A value of 2.0 indicates no autocorrelation, and a value of 2.0 to 4.0 indicates negative autocorrelation.

Can someone solve this for me with their explanation please?

Lana71 [14]

First you want to subtract 36

so it looks like this $\sqrt[4] {(4x+164)^3}=64$

Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)

${(4x+164)^3}=64^4$ which is equal to ${(4x+164)^3}=16777216$

Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]

Then you end up with the equation 4x+164=256

Then subtract 164 to both sides

4x=92

then divide 92 by 4

Then you get x=23

Ulleksa [173]

Total cards = 52

Total kings = 4

P(2 kings) = (4/52)(4/52) = 1/169

Flura [38]

The correct answer is option B which is mixture B will have the highest ratio of blue paint.

<h3>What is a ratio?</h3>

In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.

The given ratios are:-

Mixture A = $\dfrac{5}{12} = 0.41$
