The decision rule is
Fail to reject the null hypothesis
The conclusion is there is not enough evidence to support the claim
The venue will break even after selling 1000 tickets.
The value will be $70,000 at that point.
Step-by-step explanation:
Given,
Charges of band;
C(x) = 55x+15000
Per ticket charges by Venue = $70
V(x) = 70x
For breaking even,
C(x) = V(x)
Dividing both sides by 15
The venue will break even after selling 1000 tickets.
Putting 1000 in V(x)
The value will be $70,000 at that point.
