It’s most likely they will pay with cash, because credit is the 2nd more done. It’s like a inference of what the person is going to pay with based on what people pay more on.
P=0.15
P^ is the sample proportion which comes from the data
In this case the p^=12/50=0.24
The slope is m, which is 312.3
also in intercept form would be y=312.3x+18.5
X + 6 = 33
x = 27
hope this helps :D
