Regression analysis is a statistical method used to examine the relationship between a dependent variable (also known as the outcome variable or response variable) and one or more independent variables (also known as predictors or explanatory variables).
What is regression analysis?The process of regression analysis involves estimating the values of the coefficients (i.e. the slope and y-intercept) that minimize the difference between the predicted values (from the model) and the actual values (from the data). This difference is typically measured by the sum of the squared errors (SSE). The resulting line or hyperplane is called the regression line or regression model.
Once the model is built, it can be used to make predictions about the dependent variable based on new values of the independent variables. Additionally, regression analysis can also be used to test hypotheses about the relationship between the variables, and to assess the strength and direction of the relationship.
a) An appropriate hypothesis to test the association between brain size and IQ would be:
H0: There is no association between brain size and IQ (coefficient of brain size = 0)
Ha: There is an association between brain size and IQ (coefficient of brain size ≠ 0)
b) Based on the R-squared value of 6.5% and the coefficient of brain size being 0.098842, it can be concluded that there is a weak association between brain size and IQ. The coefficient suggests that for every 1000 pixels increase in brain size, there is a 0.098842 increase in IQ, which is not a large effect. Additionally, the R-squared value indicates that only 6.5% of the variation in IQ can be explained by brain size.

Determine whether the outcome is a Type I error, a Type II error, or a correct decision.
A test is made of H0: m = 45 versus H1: m is not equal to 45. The true value of m is 45, and H0 is not rejected.
Correct Decision
Type II
Type I
The true value of m is 45, and H0 is not rejected, than the correct decision is Type II.
condition:-
H0: m = 45 VS H0: m ≠ 45
The true value of m = 45
H0 is not rejected, & H0 is not rejected.
∴ here we not reject the when H0 is not true hence is is a type II error.
H0 is rejected.
∴ Here we reject the H0 when H0 is true hence it is a type I error
A type II error occurs if one fails to reject the null hypothesis when the alternative is True.
A type I blunders is a fake high-quality end, whilst a kind II errors is a false bad conclusion. making a statistical decision always includes uncertainties, so the risks of creating those mistakes are unavoidable in speculation trying out.
A type I error is a type of fault that takes place throughout the hypothesis checking out process when a null hypothesis is rejected, although it is correct and must no longer be rejected.
Decision error confer with the probability of creating a wrong conclusion while doing hypothesis checking out. when a researcher sets out to do a examine, she usually has a speculation, or a prediction of what she thinks the effects will be.

Solomon Ski Company manufactures snow skis. During the most recent accounting period, the company’s finishing department transferred 4,150 sets of skis to finished goods. At the end of the accounting period, 480 sets of skis were estimated to be 50 percent complete. Total product costs for the finishing department amounted to $285,350.
Required
Determine the cost per equivalent.
Determine the cost of the goods transferred out of the finishing department.
Determine the cost of the finishing department’s ending work in process inventory.
The various costs for Solomon Ski Company during the recent accounting period are determined as follows:
1. Cost per equivalent unit is $65.
2. Cost of finished goods transferred out from the finishing department is $269,750.
3. Cost of the ending WIP inventory is $15,600.
What is the cost per equivalent unit?The cost per equivalent unit refers to the average cost per unit based on the total production costs divided by the total equivalent units of production.
The equivalent units of production depend on the degree or percentage of completion for the various cost classes.
Data and Calculations:Transfer to finished goods = 4,150
Ending inventory = 480
Degree of completion of the ending inventory = 50%
Total equivalent units = 4,390 (4,150 + 480 x 50%)
Total production costs = $285,350
Cost per equivalent unit = $65 ($285,350/4,390)
Cost of finished goods = $269,750 ($65 x 4,150)
Cost of the ending WIP = $15,600 ($65 x 240)

Suppose that the federal budget is balanced when GDP is at potential GDP. If equilibrium GDP falls below potential, please explain how and why government transfer payments would change; how and why tax receipts would change; how and why the budget would change.
The federal budget is the difference between the income of the government and its expenditure as illustrated in the GDP.
How to explain the information?The income of the government is tax revenue and when expenditure is more than the income, the budget is said to be in deficit. Potential GDP is the maximum GDP that an economy is able to produce with the given level of resources in the long run. In times of recession, the actual GDP is less than the potential GDP, which means the output produced is less than the capability of the economy.
Inn such periods, GDP is low, unemployment is very high and aggregate demand is also very low. When the economy is in recession, the income of the people falls and thus, the tax they pay out of their incomes also falls. Therefore, the tax receipts fall due to a fall in income.
On the other hand, in recessions, the government uses expansionary fiscal policy which directly injects money by either increasing government spending or reducing the tax rate. Therefore, when the tax rate falls, the tax revenue or tax receipts fall. The government spends money on the public to increase social welfare.
The budget of the government is the difference between tax receipts and transfer payments. When the tax receipts fall and transfer payments rise. Thus, the budget of the government falls and the federal budget is said to be in deficit.

The present value of the net cash flows was $92,000.
Given,
Project costing = $92000
Profitability index = 1

The present value of anticipated future cash flows is divided by the project's initial investment to determine the PI.
A PI of at least 1.0 is considered to be a decent investment, with higher levels indicating more alluring projects.
