Answer:
3
Step-by-step explanation:
Since d represents the number of days the car is rented, Company A charges ...
40d
Company B charges ...
60 +20d
We want to find the value of d that makes these charges be the same value:
40d = 60 +20d
2d = 3 +d . . . . . . . divide by 20
d = 3 . . . . . . . . . . . subtract d
The cost is the same for 3 days.

Using a correlation Coefficient calculator, the correlation Coefficient, r for the data = 0.127
The test statistic :
T = r² / √(1 - r²) / (n - 2)
Sample size, n = 10
Hence,
T = 0.127² / √(1 - 0.127²) / (10 - 2)
T = (0.016129 / 0.3506905)
T = 0.3506905
The value of the test statistic to 2 decimal places is 0.35
