➷ You would preferably have some tracing paper so you can draw the shape and place a pen / pencil at the point and rotate it 180 degrees clockwise. (turn it by 90 degrees twice)
Here is what you should get:
P: (3, -1)
Q: (-1, -1)
R: (0, 2)
S: (2, 2)

Answer:
The approximate 90% confidence interval is;
70,244 to 70,732
Step-by-step explanation:
Here, we want to calculate the approximate 90% C.I for the situation
Mathematically;
CI = mean ± (z * SD)/√n
From the question;
mean = 70,438
SD = 645.3
n = 30
we can get z from the CI table
90% CI is same as; 1.645 z-score
So , substituting these values;
CI = 70,438 ± ( 1.645 * 645.3)/√30
CI = 70,438 ± 194
So the CI = 70,438 -194 to 70,438 + 194
= 70,244 to 70,732
