It's saying that 95% of the time the comparison from test to retest is 96% reliable.
so I would take (0.95+0.96)÷2= 0.955
then 73×0.955=69.715
then 73-69.715=3.285
so I would range the possible true score between 69.715 and 76.285
also written as 73 ± 3.285
Answer:
Since this is old, im just gonna get these points, don't wan't them to go to waste lm.ao
Step-by-step explanation:
The answer is
y^2-4x+4y-4=y^2+4y-4x-4=(y+2)²-4x - 8= 0
it is the same of x + 2 = (1/4 ) (y+2)²
the main formula is x-h= a (y-k)² so h=-2, k= - 2 and a=1/4
