A report announced that the median sales price of new houses sold one year was $211,000, and the mean sales price was $272,500. Assume that the standard deviation of the prices is $80,000. Complete parts (a) through (d) below.
If you select samples of n=2, describe the shape of the sampling distribution of X.
Choose the correct answer below.
O A. The sampling distribution will be approximately uniform.
OB. The sampling distribution will be approximately normal.
OC. The sampling distribution is skewed to the right, but less skewed to the right than the population
D. The sampling distribution will depend on the specific sample and will not have a constant shape.

my answer is$ 12

step-by-step explanation:

because 15 -2=12

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

7 is the median   7.875 is the mean
