Answer:
a) True
Step-by-step explanation:
Repeated samples are a type of samples that are used to determine the features or characteristics or a given set of data.
In repeated samples, statistical techniques are applied whereby two samples that have similar characteristics are tested or analysed under different conditions.
Repeated samples can also be called matched or paired samples.
In repeated samples , we have what we refer to as confidence intervals. These are intervals whereby the true and correct value of certain parameters such as mean, the standard deviation of a given data or distribution is determined. We have confidence interval levels of 90%, 95% and 99%.
In repeated samples, approximately 99% of all differences in sample means will fall within the bounds of the interval already computed.
With

we have

so
has one eigenvalue,
, with multiplicity 3.
In order for
to not be defective, we need the dimension of the eigenspace to match the multiplicity of the repeated eigenvalue 2. But
has nullspace of dimension 2, since

That is, we can only obtain 2 eigenvectors,

and there is no other. We needed 3 in order to complete the basis of eigenvectors.
The slope of the line is undefined because the line doesnt pass through the origin. In order to calculate the slope the line must both be straight and pass through the origin.
If a and b are supplements, their total is 180 degrees, by definition. If b and c are supplements, their total is 180 degrees, by definition.
I don't know, Sorry, but I will keep looking at it to see if I can figure it out, Sorry
