Answer:
c) is true
Step-by-step explanation:
Given are four statements. Let us check one by one
a) If the calculated value of F statistic is higher than the critical value, we reject the alternative hypothesis in favor of the null hypothesis
False, we reject H0 in favour or alternate
b) The F statistic is always nonnegative as SSRr is never smaller than SSRur.
F statistics is non negative but reason is bot SSRr and SSRur are positive
Not because SSRr is never smaller than SSRur
c) Degrees of freedom of a restricted model is always less than the degrees of freedom of an unrestricted model.
This is true because in a restricted we put constraints thus df will be less
d) The F statistic is more flexible than the t statistic to test a hypothesis with a single restriction.
False. F statistic is for testing variances while t statistic for means.
Answer: x = 4 / 2y-z
Step-by-step explanation: Move all of your terms to the left and then set your equal as 0. Then, set each of your factors equal to 0, as well.
I hope this helps you out.
Answer:
600ft²
Step-by-step explanation:
the area of a rectangle is L × W.
to get the actual area of the rectangular family room, we have to convert the measurements to (ft).
if 1 cm = 5ft...........what about.....
6 cm= ??
cross multiply..... 6 × 5 ÷ 1 = 30ft.
4cm = ??
cross multiply..... 4 × 5 ÷ 1 = 20ft.
area = L × W.
30ft × 20ft = 600ft²
