Answer:
C. rating scale test.
Explanation:
In a rating scale test, respondents are asked by researchers to rate either their products, services, or work on a scale, say one to ten. This type of test is used by researchers when they want respondents to place value on the features,products,service as contained in the questionnaire.
This type of test is also used to assess performance of employees, products,services etc inorder to achieve a particular goal.
Rating scale is also used to get more information about comparisons between two values hence an important survey method.
This is an example of variation. The
coefficient of variation, also referred to as the Spearman coefficient of
variation, is a statistical measure that informs us about the relative dispersion
of a data set. Its calculation is obtained by dividing the standard deviation<span> between
the absolute value of the average of the set and it is usually expressed as a
percentage for its better understanding.</span>
Answer:
command economy
Explanation:
In a command economy, the government is the only determinant of what is to be produced, its quantity, and price. All the factors of production belong to the government. The government or the central authority creates a central plan that guides all country's economic activities and decisions.
The private sector is absent in a command economy. The government is the only employer. Citizens do not have the freedom to choose what to buy, but rather what is available.
Answer:
Explanation:
Expected return of the portfolio is weighted average of the return of the components.
E(R) = w1 * R1 + w2 * R2
E(R) = 65% * 18% + 35% * 6%
E(R) = 11.70% + 2.10%
Expected Return, E(R) = 13.80%
Standard deviation of portfolio is mathematically represented as:

where
w1 = the proportion of the portfolio invested in Asset 1
w2 = the proportion of the portfolio invested in Asset 2
σ1 = Asset 1 standard deviation of return
σ2 = Asset 2 standard deviation of return
For risk free money market fund, standard deviation = 0 and its correlation with risky portfolio = 0

Standard deviation = 19.50%
Answer:
<u>is not</u> , <u>consume more of hamburgers</u>
Explanation:
A consumer is said to have achieved equilibrium when within his budget constraint, he purchases that combination of two goods which yield maximum satisfaction to him.
The equation for consumer equilibrium for two products is given by

In the given case,
=
=
= 6.666
=
= 8
wherein, x= pizza
y= hamburger
As is evident, the marginal utility per dollar spent is greater in case of a hamburger, the consumer is not in a state of equilibrium.
Thus, he should consume more units of Hamburgers in order to maximize his utility.
