Answer:
It is observed that the value of test statistics (19.168) is greater than the critical value (13.277), thus the rejected hypothesis, H₀ at α = 0.01.
There is enough evidence to conclude or deduce that sales were the same for all locations
Explanation:
Solution
Given that:
Object: Test whether the sales were the same for all locations by applying 1% significance level.
The Null Hypothesis H₀ : Sales were the same for all locations
E₁ = 70 +75 +70+ 50 + 35/5 = 60
The Alternative Hypothesis Hₐ : Sales were not the same for all locations
Now,
The decision rule:
the Level of Significance be α = 0.01
Degrees of freedom is df= Number of categories -1
=5-1 = 4

Answer:
D. $100
Explanation:
Given: William install 7 system per day at the cost of $300.
William install 8 system per day at the total cost of $400.
Remember, If the marginal cost curve is upward-sloping, this means that as output increase, marginal costs will also increase.
Marginal cost is an additional cost incurred in producing additional unit of output.
Now, finding additional payment that eighth customer has to pay.
Change in marginal cost=
⇒ Change in marginal cost=
∴ Change in marginal cost=
Hence, there is an increase in marginal cost by $100 as output increases, therefore, William will install eight sound systems per day only if the eighth customer is willing to pay at least $100.
