Basically there are 3 types of portfolios.
1.Working portfolio.
2.Display portfolio.

Answer:
This is a stratified random sample because a separate random sample is selected from each class
Explanation:
Stratified random sampling is an appropriate method when the population consists of mixed characteristics and you would like to ensure that every characteristic is proportionally represented in the sample. In this example, the population is the students from Central High School and the mixed characteristics are the different classes such as Freshman students, Sophomore students, Juniors and Seniors.
After the population is divided into subgroups based on characteristics, from the overall proportion of the population, you calculate how many people should be sampled in each subgroup. Random or systematic sampling can then be used to select a sample from each subgroup.
Answer:please refer to the explanation section
Explanation:
The question is incomplete, The amount that each firm must produce is not given or the Quantity/demand equation that each firm faces is not given. We use a firm's quantity/demand equation to calculate how much each firm should produce and then work out the number of firms that should exist in the industry.
let us assume quantity produced by each firm is given by this equation;
Q = 1900 + 15000Price
We need to plug the Price of $2.54 per unit Vitamin Bottle to the quantity equation. Q = 1900 + 15000(2.54) = 40 000
each firm must produce 40 000 units
Number of firms that should exist = Total Market Quantity/Firms Quantity Number of firms that should exist = 1055 560 000/40 000
Number of firms that should exist = 26389
When the price is $2.54, with each firm Producing 40000 units, 26389 firms should exist in the market to cover the total Market Quantity of 1055 560 000.
The question may provide you with the Quantity that each firm must produce, in that case you simple divide total market quantity by the firm's quantity to find number of firm that should exist.
When you are given quantity equations you use the price to work out quantity produced by each firm and then Divide the Market Quantity by Firm's quantity to find number of firms that should exist
