Answer:
<u>x = -12</u>
Step-by-step explanation:

⇒ -5x/-5 = 60/-5
⇒ x = -12
<u>The solution is x = -12</u>
The parameter used in the probability is the average number of students represented by u.
How to calculate the probability?
The confidence interval based on the information will be:
= 3.85 - 2.09(1.348 / ✓20)
= 3.22
Also, 3.85 + 2.09(1.348 / ✓20) = 4.48
The confidence interval simply means that one is 95% confident that the true mean is between 3.22 and 4.48.
