If you have the following null and alternative hypotheses for a test you are running: H 0 : p = 0.05 H a : p > 0.05 Calculate the test statistic, rounded to 3 decimal places z =

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
