it has to be higher than 1,6, because the lines go down after the y- intercept. Hope that this helps you and have a great day :)
Answer:
85%
Step-by-step explanation:
The probability of finding our satisfactory service in the three visits in a row would be the multiplication of the probability of each event.
The event is always the same. 95% of the service will be satisfactory. That is a probability of 95/100
Then the final probability would be:
<em>(95/100) * (95/100) * (95/100) = 0.85
</em>
In other words, the probability that a customer who visits three times will find our service satisfactory is 85%
The correlation coefficient for the data in the table is A. –0.993
<h3>Calculations and Parameters:</h3>
Using this formula:
We would use x and y to represent the unknowns.
n = 4
We have,
- ∑x = 42,
- ∑y = 44.37 ,
- ∑xy = 461.3
- ∑x^2 = 446,
- ∑y^2 = 494
Putting these values in the formula would bring the answer as. A. –0.993
