Answer and Explanation:

R-square measures whether the variation exists or how much dependence the independent variables on the dependent variables.

R2 = .45 which is quite low. This shows that there is not much variation. In order to increase the R2 the researcher can add more independent variables.

The below part is taken from the internet as the question was incomplete:

Sunny days = 0.5

Intercept = 2.1

The slope shows a positive relationship (direct relationship) with the dependent variable which is crime dependency.

Sunny days is the independent variable.

Intercept is also positive whereas there is significance in the p value which helps in concluding that we will reject the null hypothesis.

Which statement best describes the effects of low and high interest rates on the economy? Low interest rates encourage consumers
kirill115 [55]

The correct answer is A. Low interest rate encourage consumers to borrow and spend, while high interest rates encourage saving.

Interest rate is termed as the rate which a bank charges to its borrowers.

Nationally a good interest rat for a loan is 3.7%.

Recession and inflation are some effects of interest rate. We get to hear the federal funds rates if the interest rate falls or rises.

If the interest rate becomes high people will start to spend less to avoid the high cost.

D Maturity risk differences.

The correct answer is option C,default risk differences.

Default risk is the increase in return given to an investor to compensate the investor for the likely losses that may arise due to the inability of the borrower to make funds available to the investor on the maturity date or even in required amount.

Different debt instruments have different default risk depending on their credit rating as rated by international rating agencies.Such rating is a function of many factors,which includes:

Balance sheet position

Profitability

Liquidity strength of the company

Macro-economic factors and some others.

Liquidity refers to the ability of the company to settle obligations such as repayment of bonds and interest  when due.

Invariably,liquidity has a higher impact in determining credit rating as well as default risk of an instrument.
