What if X if [ -1 -2 4 8] +X= [-5 -1 2 1]?
Arada [10]

Answer:

[-4 1 -2 - 7]

Step-by-step explanation:

[-1 - 2 4 8] + X = [-5 - 1 2 1]

X= [-5 - 1 2 1]- [-1 - 2 4 8]

X=[-5-(-1) - 1-(-2) 2-4 1-8]

X=[-4 1 - 2 - 7]

Doss [256]

Answer:

3.83

Step-by-step explanation:

Mean of x = Σx / n

Mean of x = (14 + 19 + 13 + 6 + 9) / 5 = 12.2

Sum of square (SS) :

(14-12.2)^2 + (19-12.2)^2 + (13-12.2)^2 + (6-12.2)^2 + (9-12.2)^2 = 98.8

Mean of y = Σy / n

Mean of y = (101 + 89 + 48 + 21 + 47) / 5 = 61.2

Σ(y - ybar)² = (101-61.2)^2 + (89-61.2)^2 + (48-61.2)^2 + (21-61.2)^2 + (47-61.2)^2 = 4348.8

df = n - 2 = 5 - 2 = 3

Σ(y - ybar)² / df = 4348.8 / 3 = 1449.6

√(Σ(y - ybar)² / df) = √1449.6 = 38.074

Standard Error = √(Σ(y - ybar)² / df) / √SS

Standard Error = 38.074 / √98.8

Standard Error = 3.83
