Answer:

a. Collinearity.

Explanation:

Collinearity is a statistical term that describes a situation in which some of the independent variables are highly correlated.

This is shown when the variables to determine house sizes, is family income which is correlated with the education level, and while we combined both the factors we have another correlation with the family size.

Hence, this phenomena where two or more predictors in a regression model are moderately or highly correlated is known as COLLINEARITY.

Therefore, what should the real estate builder be particularly concerned with when analyzing the multiple regression model is COLLINEARITY.

Answer:

Net increase in operating income = $1,200

The "made in the usa" campaign was popularized by unions in an effort to influence which determinant of demand
dybincka [34]
I think the answer is TASTE or PREFERENCE of the consumer or buyer.

There are 5 determinants of demand. These are:
1) price
2) price of related goods
3) income of buyer
4) taste or preference of buyer
5) expectations

The "made in the USA" is a type of branding that will influence buyer's taste or preference. There are a lot of inference about when goods are tagged as "made in USA".

When compared with the purely competitive industry with identical costs of production, a monopolist will charge: higher price an
IRISSAK [1]

Answer: Higher price and produce less output.

Explanation:

A monopolist is the only producer of a good in the market or at least wields significant market power. As a result, they can set their own prices without regard for how competitors would react.

This would lead to a situation where the monopoly does not have to be efficient and so will produce less goods than a perfect competition would and in order to make more profit - and because of less efficiency meaning higher costs - they will charge a higher price for output.
