Acoffee shop owner offers two brands of coffee, brand "a" and brand "b". the proportion of clients that prefer brand "a" is 60%.recently, the price of brand "a" went up. the proportion of clients that buy brand "a" among the first 15 customers that enter the shop after the change in price is an estimator of the current proportion of clients that prefer brand "a".assume that the change in price has no effect on the preference of the clients. then the mean squared error (mse) of the estimator is equal to:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

i believe that the answer is

b. y-1=-2(x-4)

hope this !
