Compute the z-score corresponding to each of the values of x below. a. xequals45, sequals5, x overbarequals30 b. xequals87, muequals86, sigmaequals2 c. muequals45, sigmaequals5, xequals45 d. sequals6, xequals47, x overbarequals50 e. in parts a-d, state whether the z-score locates x within a sample or a population. f. in parts a-d, state whether each value of x lies above or below the mean and by how many standard deviations.

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)
