The probability that X is between 57 and 105 is 0.8914.

Given:

* X is normally distributed with mean=90 and standard deviation=12

* P(57 < X < 105)

Solution:

* Convert the given values to z-scores:

   * z = (X - μ) / σ

   * z = (57 - 90) / 12 = -2.50

   * z = (105 - 90) / 12 = 1.25

* Use the z-table to find the probability:

   * P(Z < -2.50) = 0.0062

   * P(Z < 1.25) = 0.8944

* Add the probabilities to find the total probability:

   * P(57 < X < 105) = 0.0062 + 0.8944 = 0.8914

Therefore, the probability that X is between 57 and 105 is 0.8914.

The name for a data value that is far above or below the rest is called an outlier.

An outlier is an observation that deviates significantly from other observations in a dataset. It is an extreme value that lies outside the typical range of values and may have a disproportionate impact on statistical analyses and calculations. Outliers can occur due to various reasons, including measurement errors, data entry mistakes, or genuine rare events. Identifying and handling outliers appropriately is important in data analysis to ensure accurate and reliable results.

When dealing with outliers, it is important to assess whether they are the result of errors or genuine extreme values. Statistical techniques, such as box plots, scatter plots, or z-scores, can be used to detect outliers. Once identified, the appropriate action depends on the nature and cause of the outliers. In some cases, outliers may need to be corrected or removed from the dataset, while in other cases, they may provide valuable insights or require further investigation.

A quick estimate of the standard deviation can be obtained using the range of the data set. One common rule of thumb is to divide the range by 4 to estimate the standard deviation, assuming a roughly symmetric distribution.

In this case, the range of the data set is from 50 to 110.

Range = Max Value - Min Value = 110 - 50 = 60

Quick Estimate of Standard Deviation = Range / 4 = 60 / 4 = 15

Therefore, a quick estimate of the standard deviation is approximately 15.

The Jacobian of the transformation of the given equation is:

∂(x, y) / ∂(u, v) =\(\frac{5uv}{v^{2} }\) - \(\frac{15u}{v^{2} }\) = 5\(\frac{u}{v}\) - \(\frac{15u}{v^{2} }\) = u(5\(\frac{u}{v}\) - 15\(\frac{u}{v^{2} }\))

To find the Jacobian of the transformation, we need to compute the partial derivatives of x and y with respect to u and v. We have:

x = 5uv

y = 3u/v

Taking the partial derivative of x with respect to u, we get:

∂x/∂u = 5v

Taking the partial derivative of x with respect to v, we get:

∂x/∂v = 5u

Taking the partial derivative of y with respect to u, we get:

∂y/∂u = 3/v

Taking the partial derivative of y with respect to v, we get:

∂y/∂v = -3u/\(v^2\)

Therefore, the Jacobian of the transformation is:

∂(x, y) / ∂(u, v) = |∂x/∂u ∂x/∂v|

|∂y/∂u ∂y/∂v|

Substituting the partial derivatives that we computed above, we get:

∂(x, y) / ∂(u, v) = |5v 5u|

|3/v -3u/\(v^2\)|

Therefore, the Jacobian of the transformation is:

∂(x, y) / ∂(u, v) = 5uv/\(v^{2}\) - 15u/v\(v^{2}\) = 5u/v - 15u/\(v^2\) = u(5/v - 15/\(v^2\))

(c) Value of the test statistic 3.184.

(d) The information disagrees with the United Nations report at the 0.01 significance level since the calculated t-value falls outside the critical value range.

(a) State the null hypothesis and the alternate hypothesis:

The mean family income for Mexican migrants is $26,450 per year

H₀: µ = $26,450

The mean family income for Mexican migrants is not equal to $26,450 per year.

H₁: µ ≠ $26,450.

(b)

Reject H₀ if t is not between -2.807 and 2.807 (critical values for a two-tailed t-test with 22 degrees of freedom and a significance level of 0.01).

(c) Compute the value of the test statistic:

To compute the test statistic (t-value), we need the sample mean, the hypothesized population mean, the sample standard deviation, and the sample size.

Sample mean (X) = $37,190

Hypothesized population mean (µ) = $26,450

Sample standard deviation (s) = $10,700

Sample size (n) = 23

t-value = (X - µ) / (s / √n)

= ($37,190 - $26,450) / ($10,700 / √23)

= ($37,190 - $26,450) / ($10,700 / √23)

= $10,740 / ($10,700 / √23)

= 3.184

The calculated t-value is approximately 3.184.

d.  To determine if this information disagrees with the United Nations report, we compare the calculated t-value with the critical values for a two-tailed t-test with 22 degrees of freedom and a significance level of 0.01.

The critical values for a two-tailed t-test with a significance level of 0.01 and 22 degrees of freedom are approximately -2.807 and 2.807.

Since the calculated t-value of 3.184 falls outside the range -2.807 to 2.807, we reject the null hypothesis (H0) and conclude that there is evidence to suggest a disagreement with the United Nations report.

Therefore, based on the provided data and significance level, the information disagrees with the United Nations report.

The VAT amount that should be paid by the contractor is Rs. 19,000.

To calculate the VAT amount that should be paid by the contractor, we need to follow the given information and calculate the necessary values step by step.

Laligurash suppliers sold construction materials worth Rs. 2,00,000 to Himchuli suppliers, making a 20% profit and adding 13% VAT.

Profit made by Laligurash suppliers = 20% of Rs. 2,00,000 = Rs. 40,000

Total amount paid by Himchuli suppliers to Laligurash suppliers = Rs. 2,00,000 + Rs. 40,000 = Rs. 2,40,000

VAT amount on the purchase for Himchuli suppliers = 13% of Rs. 2,40,000 = Rs. 31,200

Himchuli suppliers spent Rs. 6,000 for transportation cost and made a 10% profit on the purchased price (excluding VAT).

Profit made by Himchuli suppliers (excluding VAT) = 10% of Rs. 2,40,000 = Rs. 24,000

Total cost incurred by Himchuli suppliers = Rs. 2,40,000 + Rs. 6,000 = Rs. 2,46,000

Total selling price by Himchuli suppliers to the constructor = Rs. 2,46,000 + Rs. 24,000 = Rs. 2,70,000

Himchuli suppliers levied a local tax of Rs. 5,000.

To calculate the VAT amount that should be paid by the contractor, we subtract all the costs and taxes from the selling price:

VAT amount for the contractor = Selling price - (Total cost + Local tax)

= Rs. 2,70,000 - (Rs. 2,46,000 + Rs. 5,000)

= Rs. 19,000

Therefore, the VAT amount that should be paid by the contractor is Rs. 19,000.

Answer:

The correct answer is none.

Step-by-step explanation:

The correct answer is y = -1/5x + 1

To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.

m(slope) = (y2 - y1)/(x2 - x1)

m = (2 - -1)/(-5 - 10)

m = 3/-15

m = -1/5

Now that we have the slope, we can use it along with either point in the point-slope form to get the equation.

y - y1 = m(x - x1)

y - 2 = -1/5(x + 5)

y - 2 = -1/5x - 1

y = -1/5x + 1

The domain for the given function is {-1, 2, 33, 32}.

A function's or relation's domain is the set of all possible independent values that the relation can take. It is the sum of all possible inputs.

A function's or relation's range is the set of all possible dependent values that the relation can produce from the domain values. It is the sum of all possible outputs.

When dealing with sets of ordered pairs, we simply divide the pairs into x- and y-coordinates. The domain is formed by the x-coordinates, which are independent values. The y-coordinates are the dependent values, i.e. they define the range.The domain in the set of ordered pairs {(a,b); (c,d); (e,f); (g,h)} is the set of the first number in each pair (those are the x-coordinates): {a,c,e,g}. The range is the set of all the pairs with the second number (the y-coordinates): {b,d,f,h}.

Given,

The set of ordered pair =   {(-1,5) , (2,3), (33,6), (32,7)}

then,

the Domain = {-1, 2, 33, 32}
