If im understanding your post this is what i get
y − 4x = 72
+ y + 4x = 2
_________
2y= 74
Y= 72/2
Y= 36
y − 4x = 72
35-4x=72
-4x=72-35
-4x=37
X= 37/-4
X= - 37/4 or -9.25
Answer in point (-37/4, 36)
Answer:
The probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216
Step-by-step explanation:
We are given that
The variance of the scores on a skill evaluation test=143,641
Mean=1517 points
n=343
We have to find the probability that the mean of the sample would differ from the population mean by less than 36 points.
Standard deviation,




Hence, the probability that the mean of the sample would differ from the population mean by less than 36 points=0.9216
