The Normal distribution is symmetric and ranges from negative to positive infinity, while the Log-normal distribution is skewed and only takes positive values. To select the better fit for data, consider characteristics (positivity and skewness favor Log-normal, symmetry favors Normal), hypothesis testing, visualization, and statistical tests.

Let's analyze each section separately:
a) The major differences between the Normal and Log-normal distributions are:

Normal Distribution: The Normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution that is defined by its mean (μ) and standard deviation (σ). It follows a bell-shaped curve and is often used to model naturally occurring phenomena. The range of values extends from negative infinity to positive infinity.

Log-normal Distribution: The Log-normal distribution is a skewed probability distribution that arises when the logarithm of a random variable follows a normal distribution. It is characterized by its parameters mu (μ) and sigma (σ) of the underlying normal distribution. Unlike the Normal distribution, the Log-normal distribution only takes positive values.

b) Selecting which distribution fits the data better depends on the nature of the data and the research question at hand. Here are a few considerations:

1. Data Characteristics: If the data consists of positive values and the distribution appears to be skewed, the Log-normal distribution might be more appropriate. On the other hand, if the data is symmetric and unbounded, the Normal distribution may be a better fit.

2. Hypothesis Testing: If you have a specific hypothesis to test or a theoretical justification for choosing one distribution over the other, it is advisable to use that distribution.

3. Visualization: Plotting the data and comparing it to the shapes of the Normal and Log-normal distributions can provide visual insights into which distribution aligns better with the data.

4. Statistical Tests: Statistical tests such as the Kolmogorov-Smirnov test or the Anderson-Darling test can be used to assess the goodness-of-fit for each distribution and determine which one provides a better fit to the data.

In summary, selecting the appropriate distribution involves considering the characteristics of the data, the research question, and statistical tests. Visualization and hypothesis testing can further aid in determining the best fit distribution.

Answer:

a.) 13 students

b.) 53 members

Step-by-step explanation:

a.) In the given equation of y=4x+13, "x" represents how many years have gone by since the club had started. The number "13" in this equation represents the y-intercept, or the value of "y" when x = 0. Therefore, when "x" is 0 years, there were 13 students in the clubs, meaning that the original group that started the club contained 13 students.

b.) Since the question asks how many members that the club will have after their tenth year and you already know that "x" in the equation y=4x+13 represents the number of years since the club started, all you have to do is plug 10 in for "x" in the equation; so, the equation will now look like this: y=4(10)+13. Keeping PEMDAS in mind, you first multiply 4 and 10 to get 40, and then you add 13 to get an answer of 53 members after year 10.

The equivalent of 0.85 hectogram (hg) is 850 decigram (dg)

The measure is given as:

0.85 hg

As a general rule:

1 hectogram (hg) = 1000 decigram (dg)

So, multiply both sides of the above equation by 0.85

So, we have:

0.85 * 1 hectogram (hg) = 0.85 * 1000 decigram (dg)

Evaluate the product

0.85 hectogram (hg) = 850 decigram (dg)

Hence, the equivalent of 0.85 hectogram (hg) is 850 decigram (dg)

Where C1 and C2 are constants that can be determined from initial conditions.

a(d^2y/dt^2) + b(dy/dt) + cy = 0

where a, b, and c are constants.

To solve this equation, we assume that the solution has the form:

y = e^(rt)

where r is a constant. We substitute this form of the solution into the differential equation and get:

a(r^2)e^(rt) + b(re^(rt)) + ce^(rt) = 0

We can factor out e^(rt) from this equation to get:

e^(rt)(ar^2 + br + c) = 0

Since e^(rt) is never zero, we can divide both sides of the equation by e^(rt) to get:

ar^2 + br + c = 0

This is called the characteristic equation of the differential equation. We can solve for r by using the quadratic formula:

r = (-b ± sqrt(b^2 - 4ac)) / 2a

There are three possible cases for the roots of the characteristic equation:

If the discriminant (b^2 - 4ac) is negative, then the roots are complex conjugates of the form r = α ± iβ, where α and β are real numbers. In this case, the general solution is:

y = e^(αt)(C1cos(βt) + C2sin(βt))

If the discriminant is zero, then the roots are repeated and of the form r = -b / 2a. In this case, the general solution is:

y = e^(rt)(C1 + C2t)

If the discriminant is positive, then the roots are real and distinct. In this case, the general solution is:

y = C1e^(r1t) + C2e^(r2t)

where r1 and r2 are the roots of the characteristic equation.

Now let's apply this method to the given differential equation:

d^2y/dt^2 - 2(dy/dt) + 5y = 0

The coefficients are a = 1, b = -2, and c = 5. The characteristic equation is:

r^2 - 2r + 5 = 0

Using the quadratic formula, we get:

r = (2 ± sqrt(4 - 4(1)(5))) / 2

r = 1 ± 2i

Since the roots are complex conjugates, the general solution is:

y = e^t(C1cos(2t) + C2sin(2t))

Therefore, the general solution to the differential equation is:

y = C1e^(2t)sint + C2e^(2t)cost

where C1 and C2 are constants that can be determined from initial conditions.

The regression output should include the equation in the form of Y = a + b1X1 + b2X2 + b3X3, where Y is the predicted value of customer traffic, X1 is advertising expenditure, X2 is facility size, and X3 is the urban dummy variable.

To create a regression model in Excel, you can follow these steps:

Collect the data:

You will need data for customer traffic, advertising, facility size, and location.

Let's say you have collected data from 50 stores, including customer traffic, advertising expenditure, facility size, and whether the location is urban or suburban.

Open Excel and create a new spreadsheet.

Enter your data into the spreadsheet, with each variable in its own column.

Make sure the columns have headings, and the data is organized correctly.

Create dummy variables for location.

Since suburban is the base case, you can create a new column for an urban dummy variable.

Assign a value of 1 to urban and 0 to suburban.

Create a scatter plot of the data to see if there is a relationship between customer traffic and the other variables.

To create the regression model, go to the "Data" tab and click on "Data Analysis.

Select "Regression" from the list of options and click "OK."

In the regression dialog box, enter the input range for your independent variables (advertising, facility size, and the urban dummy variable).

Enter the output range for the dependent variable (customer traffic).

Check the "Labels" box if you have included column headings in your data.

Check the "Output Range" box to specify where you want the regression output to appear.

Click "OK" to run the regression analysis.

Review the regression output to see the coefficients for each variable and the R-squared value.

To predict customer traffic for an urban location with advertising of \($28\)hundred and a facility size of 2.7 acres, you can use the regression equation.

Substitute the values for X1, X2, and X3 into the regression equation and calculate the predicted value of Y.

You may need to adjust the decimal places of the coefficients and predicted value to match the precision of your data.

Once you have created your regression model, you can use it to predict customer traffic for different combinations of advertising, facility size, and location.

The odds of drawing a queen at random from a standard deck of cards are 1 in 13, or 7.7%.

Hence answer is true.

The odds of drawing a queen at random from a standard deck of cards can be calculated by dividing the number of queen cards by the total number of cards in the deck.

There are 4 queens in a standard deck of 52 cards,

so the odds can be expressed as a fraction,

⇒ 4/52

This fraction can be simplified by dividing both the numerator and denominator by the greatest common factor, which is 4.

⇒ 4/52 = 1/13

Hence,

The odds of drawing a queen at random can be expressed as 4:52, which can be simplified to 1:13. This means that there is a 1 in 13 chance of drawing a queen from the deck.
