Step-by-step explanation:
here's the answer to your question
Answer:
H0 : ρ = 0
H1 : ρ ≠ 0
Test statistic = 1.197
Pvalue = 0.2335
There is no correlation between the two variables
Step-by-step explanation:
The null and alternative hypothesis :
H0 : No correlation exist,
H1 : Correlation exist
H0 : ρ = 0
H1 : ρ ≠ 0
Test statistic, T = r / √(1 - r²) / (n - 2)
T = 0.067 / √(1 - 0.067²) / (320 - 2)
T = 0.067 / √(0.995511 / 318)
T = 0.067 / 0.0559512
T = 1.197
The Pvalue obtained from the Rscore, at df = 320 - 2 = 318 is 0.2335
α = 5% = 0.05
The Pvalue > α ; we fail to reject the null and conclude that, there is no correlation between the two variables.
Slope intercept form is

where

is the slope
and

is the y-intercept
they give us that the slope is 2
so our

then to find

, we temporarily plug in the point they gave us for x and y
so

and solve for

3 = 2 + b
1 = b
so our

put this together and we get

as our answer
Answer:683 km
Step-by-step explanation:
Answer:
The value of x is approximately 0.3684.
Step-by-step explanation:
Given:

We need to solve the proportion.
Solution:
Now we can see that;
In given equation one number is fraction and other number is whole number.
Now To make whole number into fraction we will divide by 1.
hence the whole number will be equal to;

Now the new equation will be;

Now by cross multiplication we get;

Now dividing both side by 19 we get;

Hence the value of x is approximately 0.3684.
