Let R unrestricted and R restricted be 0.4366 and 0.4149 respectively. The difference between the 9) unrestricted and the restricted model is that you have imposed two restrictions. There are 420 observations. The F-statistic in this case is: A) 10.34 B) 4.61 C) 7.71 D) 8.01

Complete Question

Let R unrestricted and R restricted be 0.4366 and 0.4149 respectively. The difference between the 9) unrestricted and the restricted model is that you have imposed two restrictions. There are 420 observations. The F-statistic in this case is:_______

A) 10.34

B) 4.61

C) 7.71

D) 8.01

The  correct option is  D

Step-by-step explanation:

From the question we are told that

    The  

     The  

       The  number of observation is  n=  420

Generally the number of independent variables is  k()  =  3

Then the number of  restriction is  (i.e ) is  q =  2

  Generally the F-statistics is mathematically represented as

substituting values

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

is only a line? i think so
