Answer:
D) substantial, but not complete, performance
Explanation:
Even though Moses breached his contract with Noelle, most part of the contract was performed. The most significant part of the contract was the apartment itself, not the air conditioning system. For a material breach to exist Moses should have failed to perform in a greater way, not just the air conditioning. Probably Noelle should get a discount on the price of the apartment so that she can get the air conditioning system installed.
The fact that Noelle stopped paying for the apartment just because of this is a little overreacting. For example, if I buy a used car and the previous owner forgets to give me the spare tire, I cannot stop paying because it may be worth money but proportionally it's a small amount.
1) cost per child = 400
2) cost per child for these additional 20 children = 460/ 20 = $ 23
3) the average cost per child = (400 + 460)/ 21 = 860 / 21 = $ 40. 952
4) The above result show that the cost of polio vaccine is less which is only $23. But the setting up immunization program & other necessary associated works have adds up to a higher cost of $ 40. 952. This can be reduced if more nos. of children are involved in the immunization program.
Also, the cost of setting up immunization program will be same for one child or more than one. Only the cost of polio vaccine will vary when the nos. of participating will increase.
I think the reason why the normality of these two proportions is assumed because of n(3.13159) greater than or equal to 10 and n(1 - 3.13159) is greater than or equal to 10. Therefore, for each sample in this research, it must be taken separately.
