Let be the line given by the vector equation
.
First, we use the director vectors of the lines L1 and L2 to get the
vector equation of the plane containing them, which we denote by . This is,
We observe that . Therefore, the vector equation of
defines a plane and
is a normal vector to
Finally, the vector equation for the wanted plane, which we denote by , is
Thus, if , then
and since
is parallel to
, then it is perpendicular to
.
Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
Given : Sample size : , which is a large sample , so we apply z-test .
Sample mean :
Standard deviation :
Significance level :
Critical value :
Now, a confidence interval at the 95% level of confidence will be :-
