Answer: A
Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below
Margin of error = critical value × σ/√n.
Where n is the sample size.
As we can see that the critical value is a constant and the population standard deviation.
Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.
If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.
we have to find address of element -5 in the matrix
We know that
horizontal line represents number of rows
vertical line represents number of columns
We can see that
-5 is in third row
and -5 is in second column
Suppose, we have element in matrix

Here , m is number of rows
and n is number of columns
so, we got


now, we can plug these values
and we get
