<span>This is false. An increase in demand is more major than an increase in quantity demanded. Quantity demand refers to the demand of a product at a particular price and is only a movement on the demand curve. An increase in demand would cause the demand curve to shift which is more major than a movement and it encompasses the entire relationship between price and demand.</span>
The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
Using Tuckman’s stages of group development, we know that Elaine’s group is going through a stage called storming.
In this stage of group development, aside from having difficulties in adjusting to their roles, Elaine’s group and group members would also experience disagreements regarding priorities, tensions between one another, hostility with each other, and there would also be cliques forming inside the group.
Answer: 187%
Explanation:
The percentage increase in the price of dozen egg would be:
= ( 2.75-0.96) × 100/ 0.96
= 1.79 × 100 / 0.96
= 186.45%
The percent increase in the price of dozen egg = 187%
