Answer:

The common problem i encounter mostly is the statistical modelling problem.

In this scenario we choose best combination of independent variables for the hypothesis testing. the independent variable shows the significant effect on dependent variable so we keep it in modelling.

My null hypothesis would be that there is no significant effect of independent variable on dependent variable.  for my alternative hypothesis there exist is significant effect of independent variable on dependent variable.

Explanation:

The common problem I face daily is the statistical modelling problem which is the selection of relevant independent variable for prediction modelling.

In this example to select the best combination of independent variables we use hypothesis testing. if the independent variable has significant effect on dependent variable then the independent variable shows the significant effect on dependent variable so we keep it in modelling. In this way the model gets improved.

Since there are always two variables or two categories. hence it has a two sample test.

The Hypothesis can be shown below:

Null hypothesis:

H0: There is no significant effect of independent variable on dependent variable.

Alternative hypothesis:

Ha: There is significant effect of independent variable on dependent variable.

According to Davidson, the republican and the democrat philosophies are two fundamentally different economic philosophies that impact the debt crisis faced by the United States.

QUESTION 4.
Towards the end of his talk, Davidson says he fears that the longer we delay any solution, the more the world will look to the U.S. not as the bedrock of stability in the global economy, but as a place that can't resolve its own fights. He explains that the higher interest rates are going to be, the quicker we're going to have to face a day of horrible calamity.

allochka39001 [22]

Answer:

$2,46500

Explanation:

Self-employment Earnings are profits made from carrying on a "trade or business" as a sole proprietor, an independent contractor, or some form of partnership. For a trade or business, to be considered self employment, does not have to be profitable, and it shouldn't be a full time thing but profit must be your motive.

To calculate your self employment income Subtract ordinary and necessary trade or business expenses from the gross income you derived from your trade or business.

Note that, the amount subject to self-employment tax is 92.35% of your net earnings.

Remember you pay income tax on your profits only, not your total income. Subtract your business expenses from your total income. This is the amount you will pay income tax on.

For Karlie

HI taxable Self employment earnings = $85,000

HI Self employment tax = ($85,000 × 0.29)

= $24650

Hence the portion of her earnings subjected to two parts of security tax is #2,46500.
