Answer:
Equation = x²+(y+3)²=5²
Step-by-step explanation:
The question is on equation of a circle in a center-radius form
The general equation is
(x-h)² + (y-k)² = r² where the center is at (h,k) and the radius is r
Given
point P=(3,1) and point Q= (-3,-7)
<u>Find the diameter PQ </u>
d= 10 units hence radius is 10/2 =5 units
Find the center of the circle
center =[ (x₁+x₂)/2, (y₁+y₂)/2]
center=[ (3+-3)/2 , (1+-7)/2]
center= [ 0/2 ,-6/2]
center= [0,-3]
Equation = x²+(y+3)²=5²
a. The standard error is equal to the standard deviation divided by the square root of the sample size:
SE = (23 ppm)/√18 ≈ 5.42 ppm
b. The t statistic is given by the difference between the true and sample means, divided by the standard error:
t = (192 ppm - 180 ppm)/SE ≈ 2.21
c. The p-value is approximately 0.0204.
d. Since p < 0.05, the difference is significantly different, so we reject the null hypothesis.
e. A type I error might have occurred, since it's possible that the null hypothesis was true, but we ended up rejecting it.
