The F-statistic in the multiple regression model .

(A) tests a joint hypothesis that all of the coefficients are equal to zero at the same time.
(B) is used to measure a regression "goodness of fit."
(C) tests the significance of the R-squared statistic.
(D) tests a common null for all regression slope coefficients.
(E) All of the options are correct.

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
