Step-by-step explanation:
Consider the provided information.
Part (A)
A random sample of 100 students from a large university.
Increasing the sample size decreases the confidence intervals, as it increases the standard error.
If the researcher increase the sample size to 150 which is greater than 100 that will decrease the confidence intervals or the researcher could produce a narrower confidence interval.
Hence, the correct option is true.
Part (B)
The researcher wants to identify that whether there is any significant difference between the measurement of the blood pressure.
Therefore, the null and alternative hypothesis should be:

Answer:
N is (8,5)
Step-by-step explanation:
Find the difference between M, and A, then add it to the M coordinates
The difference between M (x) and A (x) is 3, so you have to add 3 to M's x coordinate to get the N's x coordinate.
Do the same for the y coords and you will get (8,5)
