<h3>What is null hypothesis?</h3>

Conjectures used in statistical tests, which are formal techniques for drawing conclusions or making judgments based on data, include the null hypothesis and the alternative hypothesis.
The hypotheses, which are based on a sample of the population, are suppositions regarding a statistical model of the population. The tests are essential components of statistical inference and are frequently used to distinguish between statistical noise and scientific claims when interpreting experimental data in science.
The null hypothesis, which is the statement being tested in a test of statistical significance, is typically a declaration of "no effect" or "no difference," and the test of significance is intended to evaluate the strength of the evidence against it

Molodets [167]

Answer:

Increase in income= $5,000

Explanation:

Giving the following information:

Selling price $ 110,000 ($110)

Variable expenses 60,000 ($60)

Contribution margin 50,000 ($50)

Fixed expenses 30,000

Net operating income $ 20,000

The company is considering a reduction in the selling price by $10 per unit and an increase in the advertising budget by $5,000. This will increase sales volume by 50%.

Increase in income= unitary contribution margin* sales in units - new fixed costs

New Income= 40* (1000*1.5) - 35,000= 25,000

Increase in income= $5,000

The Great Depression was the worst economic disaster in U.S. history in terms of declines in real GDP and increases in the unemp

KatRina [158]

Answer: -27.2%

Explanation:

The Real GDP can be calculated using the formula for calculating the Price Deflator which is the current price level for the year.

Price Deflator = (Nominal GDP / Real GDP) * 100

Real GDP = (Nominal GDP/ Price Deflator ) * 100

1929

= (103.6/11.9 )* 100

= $870.588

1933

= (56.4/8.9) * 100

= $633.70787

Percentage Change

= (870.588 - 633.70787) / 870.588

= 0.272

= -27.2%

GDP changed by -27.2% over the 4 year period between 1929 and 1933
