Which of the following illustrates the law of demand? a. Jorge buys fewer pencils at $2 per pencil than at $1 per pencil, ceteri
s paribus. b. Chen buys more ice cream at $4 per half-gallon than at $3 per half gallon, ceteris paribus. c. Karissa buys fewer sweaters at $50 each than at $35 each, ceteris paribus. d. a, b, and c e. a and c
1 answer:
Answer:
e. a and c
Explanation:
The law of demand states that the higher the price, the lower the quantity demanded and the lower the price, the higher the quantity demanded. This occurs because of the law of diminishing marginal utility.
The law of diminishing marginal utility states that the more of a commodity is consumed, the lower the utility derived from the consumption of the product.
It follows that Jorge and karissa would demand less of pencils and sweaters as their prices rise.
The demand curve is usually downward sloping to illustrate the law of demand.

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
