Step-by-step explanation:

Potential type of statistical error would be Type I statistical error.

What is statistical error?

The term "error" (also known as "statistical error") refers to the discrepancy between a value obtained through a data gathering procedure and the population's "actual" value. The data are less representative of the population the higher the inaccuracy. Both sampling error and non-sampling error can have an impact on data.

Given that:

two sided test of hypothesis is giving 0.05 level of significance.

and statistic resulting from the analysis was 1.23.

According to statistic result,

the results are not statistically significant because the p-value > 0.05.

So, Here we can say that it follows the Type I statistical error.

Hence, potential type of statistical error would be Type I statistical error.

The total cost of the engagement ring is $10,975. The sales tax is calculated as follows: $10,000 x 0.0975 = $975.

A sales tax is a type of consumption tax that local or state governments apply on the sale of products or services that consumers pay for when they make a purchase. When a company has a link to the jurisdiction in some way, it is responsible for collecting sales tax and remitting payment to the government.

It is only imposed and paid when the taxable supply is produced while engaging in a "taxable activity". Taxes should be based on the value of the goods or service. Because of the way the sales tax is structured, consumers are required to bear the majority of the tax burden. Because sales tax is an indirect tax, this is true.

The options that is not a key feature of the piecewise function h(x), defined as x² - 5 for 0 ≤ x ≤ 3, and -log₃x for x > 3 is the option;

A piecewise function is a function that maps the input variable with a different definition, depending on the interval of the input variable.

The piecewise function is presented as follows;

h(x) = x² - 5 for 0 ≤ x ≤ 3

h(x) = log₃x for x > 3

The domain of the function, f(x) which is the set of the x-values of the function is therefore; 0 ≤ x ≤ 3, and x > 3

Therefore; The domain of the function is 0 ≤ x < ∞, which in interval notation is; [0, ∞)

The range of the function x² - 5 is -5 ≤ x ≤ 4

The range of the function -log₃x, where x > 3 is -∞ < h(x) < -1

The range in interval notation is therefore; (-∞, 4]

Therefore, the range of h(x) is not (-∞, ∞)

The y-intercept is the point the graph intersects the y-axis, and where x is zero, which indicates;

The y-intercept is the point h(0) = 0³ - 5 = -5

Therefore, the y-intercept is the point (0, -5)

The end behavior of the function, h(x) is as x → ∞, -log₃x → -∞

Therefore, the option that is not a key feature of the function f(x) is the option; The range of h(x) is (-∞, ∞)

Answer:

g(f(x)) = x² + 1.

Step-by-step explanation:

To evaluate g(f(x)), we need to first evaluate f(x) and then plug the result into g(x). Since f(x) = x² - 1, we have g(f(x)) = g(x² - 1). Plugging this into g(x), we get g(x² - 1) = (x² - 1) + 2. So the final result is g(f(x)) = x² + 1.

Here's a step-by-step breakdown:

Note that this is only the case if f(x) and g(x) are defined for all values of x. If either function is only defined for certain values of x, then the result of g(f(x)) will depend on the specific input value used.

The approximate probability that the next 100 sunday customers will spend an average of at most $28 is 0.97725

This theorem limits the central value (mean) of a sample measure to the mean value of the population from which the sample was drawn. There are two versions of this set, average and ratio respectively. This is true only if each sample is the same size and that size matters.

We have given that,

Mean , μ = $32

Standard deviations, σ = $20

sample size, n = 100

The probability that the test 100 sunday customers will spend on average of at most $28.

Using formula,

Standard error = 20/Sqrt(100) = 2

Test- statistic, Z = (x -μ)/S.E

here we have, x = 28 , S.E = 2 , μ = 32

=> Z = ( 28 - 32)/2 = - 4/2 = -2

Now, the approximate probability value, P(X≤ x )

is P(X≤ 28) = P(X - μ / S.E < 28- 32/2) = P(Z≤ -2)

= 1 - P(Z>-2) = 1- P(Z< 2) = 1 - 0.02275 = 0.97725 To learn more about Central Limit Theorem, refer:

A minimax problem minimizes the maximum value of a number of decision variables and the maximin problem maximizes the minimum value

We know that a minimax problem minimizes the maximum value of a number of decision variables. It is sometimes applied to minimize the possible loss for a worst case (maximum loss) scenario. On the other hand a maximin problem maximizes the minimum value. Generally it is used to maximize the minimum objective (such as profit or revenue) for all potential scenario.

To solve the  optimization problem for maximum :

First we find the derivative of the function.

Set the derivative equal to 0 and solve for x. This gives the x-values of the maximum and minimum points.

Now substitute those values of x back into the function to find the corresponding values of y. This will give the maximum and minimum points of the function.

Therefore, the maximin problem maximizes the minimum value  of a number of decision variables.

In ΔFGH, the measure of m∠F=54°, the measure of m∠G=90°, and m∠H = 36°

From the question, we have the following parameters that can be used in our computation:

The sum of angles in a triangle is 180°

So, we have the following representation

m∠F + m∠G + m∠H = 180°

Substitute the known values in the above equation, so, we have the following representation

54 + 90 + m∠H = 180°

Evaluate the sum in the above equation

This gives

144 + m∠H = 180°

Collect the like terms

m∠H = 180 - 144°

Answer:

The correct answer is A. hire employees.

During a boom, or an economic expansion, businesses typically experience increased demand for their products and services. This often leads to higher profits and sales, and as a result, many businesses will choose to hire additional employees to help meet the increased demand. Hiring employees allows businesses to increase their production and sales, and it can also help them to capitalize on opportunities for growth and expansion.

The other answer choices, cutting jobs (B) and saving cash (C), are not typically associated with a boom. Cutting jobs would be more likely to occur during a recession or a downturn in the economy, when businesses are trying to reduce costs and improve their bottom line. Saving cash, on the other hand, is something that businesses might do during any economic conditions, as it can help them to build up a financial cushion and prepare for unexpected events. However, during a boom, businesses are more likely to focus on expanding their operations and taking advantage of the increased demand for their products and services.

Barry will be responsible for covering the entire $1,200 deductible. The remaining costs will subsequently be split between him and the insurer in a ratio of 20% to 80%, although he will not be required to pay more than $5,000.

He will consequently pay the following total out of pocket:

= Deductible + ( 20% x (Medical expenses - deductible)

The city that she should predict that the home is in is given as follows:

Smavile.

We are given the linear regression equations for each town, which predicts the value of a home with a square feet.

Then the prediction of the city is given by the one whose prediction for a input of 2800 square feet gives the least residual relative to 280, that is, the value that has the least absolute difference relative to 280.

For Smaville, the equation is given as follows:

p = 150 + 0.041a.

Hence the estimate of the cost for a estate with 2800 square feet is of:

p = 150 + 0.041(2800) = 264.8.

For Fancyville, the equation is given as follows:

p = 250 + 0.198a

Hence the estimate of the cost for a estate with 2800 square feet is of:

p = 250 + 0.198(2800) = 804.4.

Smavile has the least residual, hence is the prediction.
