A regression by a sample of 10 observations gives: Score=49.5+1.96 Study Hours. The sample mean of study hour is 10.5 and sum of
1 answer:
Answer:
0.1463
Step-by-step explanation:
Number of observations = 10
Sample mean = 10.5
Sum of standard deviation = 264.5
X = 14
We are to calculate The leverage statistic for study hour 14 using the data above
= 1/10 + (14-10.5)²/264.5
= 1/10 + 3.5²/264.5
= 0.1 +12.25/264.5
= 0.1+0.04631
= 0.1463 is the leverage statistic for the study

Hello!
You can use the Pythagorean Theorem
C is the hypotenuse which is the line across the diameter
a and b are the other sides
You have to find the bottom side of the triangle
9 - 6 = 3
Put in the values you know
Square the numbers
Add
take the square root of both sides
The answer is
