Okay, so the formula for a confidence interval is
test statistic +/- (critical value)(standard deviation of statistic
44 +/- (invNorm(area: 0.05, u=0, std:1))(14.5)
44 +/- 23.85
(20.15, 67.85)
hope this helps :)
Answer:
Below.(0)
Step-by-step explanation:
Step by step.
So we know that the tens digit is after the ones place so?
The ones are 6. That means the digit in the tens place is
0.
Answer:
if area is given than use formula=πd²/4
if circumference=πd

$29 will be their consumer surplus.
Consumer surplus is the difference between how much a consumer is willing to pay and how much a consumer actually does pay.
$12.00 + $15.00 + $23.00 = $50.00 (How much the consumer actually pays)
$23.00 + $26.00 + $30.00 = $79.00 (How much the consumer is willing to pay)
$79.00 - $50.00 = $29.00 (Consumer surplus)
