Lablixoy if 2 = ax + by and r is the correlation cofficient between the two that is x and y. you have to show that 82² = 2²0x² +6² 8y² +2abl You also have to show that the correlation coefficient to between two handom variables X and Y and is given by r^² (0x² + y²-0x²³x- y²) 25² x oy'' from the above data Ox, oy and Ox qure the Standard deviations of X₁ and X-Y nespectively. Please use the formala (STND).

Question
I post the questions few times but all times tutors gave the wrong solution, i give them 1 downvote. Don't answer my questions again who already gave me the answer.now i will give them multiple down votes. I also give you the multiple times down votes who will give me the wrong answer for my Statistics questions. Don't reject my question, if you don't know the answer, leave it for other tutors.
if 2 2 = ax + by and r is the correlation cofficient between the two that is x and y. You have to show that 82 = a²0x² +6²³y² +2ablx@y You also have to show that the correlation coefficient to between two handom Vapiables X and Y and is given by r^² (0x² + y² - 0x²³x- y²) 28 x0y¹` from the above data Ox, AY and Ox sure the Standard devations of X₁, and X-Y nespectively. please use the formalia (STND).

Question: Suppose that aproduct is produced in the three factorks K, Y SZ. it is Kricion that factory x produces thrice as many as items as factory y, and that factory yaudz produces the Same mmber of items. Assume that it is Known that & pareant of the items produced by the earn of the Factory and and are deffective. Assume that it is known that three factories are deffective while the sperent of these moufactured by factoring y are diffective- All the items produced in the three factories are shocked and an tem of product is selected fandom. What is the probability that this item is defective? if an itm is Selected at random is found to be defective, What is the probability that it was produced factory X₁ Y andz. Use the TALMT formula! 06/08/2022 22-00-
