Testing multiple exclusion restrictions with the F test and R-squared figures Suppose your friend Jacques needs your assistance testing five exclusion restrictions in a multiple linear regression model at the 95% level. Specifically, his null hypothesis is that β6 ,..., β10 are all equal to 0, after controlling for the independent variables x1 ,..., x5. The original, unrestricted model consisted of 10 population slope parameters, β1 ,..., β10, plus an intercept parameter β0 and was estimated using a random using a random sample of 440 observations. You ask Darnell for the residual sum of squares from the restricted and restricted models. He says he lost those figures, but he did save the R- squared values. The R-squared for the unrestricted model is 0.237, while the R-squared for the restricted model is 0.234.
Since the unrestricted model hasdegrees of freedom, while the restricted model hasthe number of exclusion restrictions must be q =.
Note: The critical value for the F-distribution, at the 95% level, is 2.6.
After computing the F-statistic, you advise Darnell that because the F-statistic is he shouldthe null hypothesis that β6 ,..., β10 are jointly significant.

only 10/60 isn't equivalent

hope this : )

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

the root or roots of a polynomial are the values of the variable that makes the polynomial equal to 0. we can find the roots of a polynomial making the expression equal to 0 and then, isolating the variable (it it has just one variable).

for example, given the following polynomial:

the root or zero of the polynomial, can be found by making the expression equal to 0, and then, isolating the variable, so, finding the root we have:

therefore, we have that the root of the polynomial is equal to 2.

we must remember that the number of roots that a polynomial can have, will depend on the degree of the polynomial, a first degree polynomial have will have one single root, a second degree polynomial (quadratic expression) may have two roots and so.

hence the correct option is:

b. a value of the variable that makes the polynomial equal to zero.

have a nice day!
