Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Sample size, n = 39
Correlation Coefficient, r = 0.273
The hypothesis test to examine if there is a positive correlation :
H0 : ρ = 0
If there is a positive correlation, then ρ greater than 1
H0 : ρ > 1
The test statistic :
T = r / √(1 - r²)/(n - 2)
T = 0.273 / √(1 - 0.273²)/(39 - 2)
T = 0.273 / 0.1581541
T = 1.726
The Pvalue using a Pvalue calculator can be be obtained using df = n - 2, df = 39 - 2 = 37
The Pvalue = 0.0463
α= .10 and α= .05
At α= .10
Pvalue < α ; Hence, we reject H0 and conclude that a positive correlation exists
At α= 0.05 ;
Pvalue < α ; Hence, we reject H0 and conclude that a positive correlation exists

Answer:
H is not a solution
Step-by-step explanation:
plug each point into the equation and see which one does not work.
F(-3,6): 4(-3) + 3(6) = 6, -12 + 18 = 6, 6=6
G(0,2): 4(0) + 3(2) = 6, 6=6
H(1,-2): 4(1) + 3(-2) = 6, 4 - 6 =6, -2=6
J(3,-2): 4(3) + 3(-2) = 6, 12 -6 = 6, 6=6
H is not a solution
Answer:
w = 25
Step-by-step explanation:
- 45+30 = 100 - w
- 75 = 100 - w
- w = 100 - 75
- w = 25
