Acompany has recorded data on the daily demand for its product (y in thousands of units) and the unit price (x in hundreds of dollars). a sample of 9 days demand and associated price resulted in the following data. x(xi−x¯)(yi−y¯) = 5930 x(xi−x¯) 2 = 2586 ¯x = 14 ¯y = 41 sse = 124 ssr = 980

(a) using the above information, develop the least-squares estimated regression equation.
(b) compute the coefficient of determination.
(c) calculate an unbiased estimate of σ 2 , the varaince of the error term .
(d) perform an f test and determine whether or not there is a significant linear relationship between demand and unit price. let α = 0.05.
(e) perform a t test to determine whether the slope is significantly different from zero. let α = 0.05.

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

answer: 4 (:
