Answer:
$15
Step-by-step explanation:
Can't help you with the drop down, as we need to know the info for Station A to be able to compare it with Station B, however, the cost for charging a car at Station B for 4 hours is:
use f(x) = 3x + 3 as the value of x = 4 falls in this function's interval
So f(4) = (3 x 4) + 3 = 15
So it will cost $15 for a car to charge for 4 hours at Station B.
The answer is 392 because 560 multiplied by .7 is 392
The critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881
<h3>How to determine the critical values corresponding to a 0.01 significance level?</h3>
The scatter plot of the election is added as an attachment
From the scatter plot, we have the following highlights
- Number of paired observations, n = 8
- Significance level = 0.01
Start by calculating the degrees of freedom (df) using
df =n - 2
Substitute the known values in the above equation
df = 8 - 2
Evaluate the difference
df = 6
Using the critical value table;
At a degree of freedom of 6 and significance level of 0.01, the critical value is
z = 0.834
From the list of given options, 0.834 is between -0.881 and 0.881
Hence, the critical values corresponding to a 0.01 significance level used to test the null hypothesis of ρs = 0 is (a) -0.881 and 0.881
