Answer:
a)
b)
c)
Step-by-step explanation:
Part a
For this case we know that the degrees of freedom are:
And we want a right tailed test so then we need to find in the t distribution with degrees of freedom =15 a critical value who accumulate 0.05 of the area in the right and we got:
Part b
For this case the significance is the degrees of freedom are:
And since is a left tailed test the critical value for this case would be:
Part c
For this case the significance is and the degrees of freedom are:
And since is a two tailed test the critical values for this case would be:
Answer:
A. E
B. FEI, FGI, EGI
C. collinear
D. 0 times
Step-by-step explanation:
A. Lines m and l intersect at point E (the point which lies on both lines, in other words their common point)
B. A plane can be named using three points which do not li on the same line, so another name for the plane Q is FEI, FGI or EGI
C. Coplanar points are three or more points that lie on the same plane, collinear points are two or more points that lie on the same line. Two points D and E are collinear.
D. Parallel planes never intersect, so there are 0 times for planes P and Q to intersect.
