Answer:
If the statement is true, lines a and b are parallel
Step-by-step explanation:
This is due to lines intersecting with line m at identical angles.
Answer:
true
Step-by-step explanation:
In such type of questions, all that you are supposed to do is, use basic mathematics to eliminate any one of the given two variables.
Check out the equations if in case you can multiply any of the given ones with a -1 and add the two equations,eliminating one of the variables.
Answer:
A. The first equation is for sample data; the second equation is for a population.
Step-by-step explanation:
The first equation is y = 
, this is the equation for sample data as the intercept (
) and the slope parameter(
) both are calculated then we have got this and these values are not taken as given.
The Second equation is 
, this is the equation for population data as we can't calculate these 
and 
as we take these values as given and also we do testing for 
parameter using t test and it is sure that testing is always done on population data not on sample data.
Answer:
E) The width of Sue's interval will be narrower than Javiers
Step-by-step explanation:
In confidence intervals, as sample size increases, the width of the confidence interval decreases.
