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.
Answer:
Step-by-step explanation:
<u>Given function:</u>
The function is plotted and it is below.
−13=7y+64
Step 1: Flip the equation.
7y+64=−13
Step 2: Subtract 64 from both sides.
7y+64−64=−13−64
7y=−77
Step 3: Divide both sides by 7.
7y
7
=
−77
7
y=−11
