Answer:
($2.123 ; $2.149)
Step-by-step explanation:
The prediction interval is expressed as :
Predicted value ± standard Error
Predicted value = $2.136
Standard Error = $0.013
Prediction interval :
Lower boundary = $2.136 - $0.013 = $2.123
Upper boundary = $2.136 + $0.013 = $2.149
($2.123 ; $2.149)
B.) The prediction interval provides a range for which the predicted value or price should fall Given a certain degree of probability. If the true value falls within this interval, then, our prediction would be deemed to have occurred not by chance.
Since the actual price within the predicted price interval, then I agree with the judge's Decison that the price was not artificially depressed.
Y+-9=3/4x+6 | y=mx+b m=slope b=y-intercept
divide -9÷-9
y=3/4x+6+-9
y=3/4x+-3
m=3/4
b=-3
I want to say the answer is 9
Multiply both sides by 6
(b-4)/6*6= b-4
b/2*6= 3b
Rewrite the equation
b-4= 3b
Subtract b from both sides
-4=2b
Divide both sides by 2
-2=b
Final answer: b=-2
Due to the common probability formula I can solve that task. Refering to the task you gave, we have all the information we need. We solve it like that:
So the answer is the first option <span>
