Question

refer to the values of (x - \\(\bar{x}\\)) and (y - \\(\bar{y}\\)) in the table below, and compute the values of (x - \\(\bar{x}\\))(y - \\(\bar{y}\\)), round the results to three decimal places.

x - \\(\bar{x}\\)	y - \\(\bar{y}\\)	(x - \\(\bar{x}\\))(y - \\(\bar{y}\\))
-3.3	-60.66	(-3.3)(-60.66) =
-0.3	22.64	(-0.3)(22.64) =
3.2	56.44	(3.2)(56.44) =
6.7	82.94	(6.7)(82.94) =

calculate the sum \\(\sum(x - \\(\bar{x}\\))(y - \\(\bar{y}\\))\\).
\\(\sum(x - \\(\bar{x}\\))(y - \\(\bar{y}\\))\\) = |

Explanation:

Step1: Calculate second row product

$(-3.3)\times(-60.66)=200.178$

Step2: Calculate third row product

$(-0.3)\times(22.64)= - 6.792$

Step3: Calculate fourth row product

$(3.2)\times(56.44)=180.608$

Step4: Calculate fifth row product

$(6.7)\times(82.94)=555.698$

Step5: Calculate sum

$638.568+200.178 - 6.792+180.608+555.698 = 1568.26$

Answer:

$200.178$
$-6.792$
$180.608$
$555.698$
$1568.26$
