Answer:
\(f^-1(x)=x-4\)
Explanation:
\(f(x)=x+4\\y=x+4\\\)
We first replace f(x) with y.
We then switch x and y.
\(x=y+4\)
We then find y in terms of x in our new equation.
\(y=x-4\)
We then replace y with \(f^-1(x)\).
\(f^-1(x)=x-4\)

Given a sample size 51 yeliding a sample variance 81 compute the confidence interval for variance at 5%
Answer:
Explanation:
The confidence interval for variance at 5% is (62.3, 99.7).
To calculate the confidence interval, the degrees of freedom (df) needs to be calculated first. This is computed as df = n - 1, where n is the sample size. In this case, df = 51 - 1 = 50.
The critical value for a 95% confidence interval is then calculated using the chi-square distribution with 50 degrees of freedom. This value is 68.25.
The upper and lower bounds of the confidence interval are then calculated as:
Lower bound = sample variance / chi-square critical value = 81 / 68.25 = 1.19
Upper bound = sample variance * chi-square critical value = 81 * 68.25 = 5.51
The confidence interval for variance at 5% is therefore (1.19, 5.51), or (62.3, 99.7) rounded to the nearest whole number.

The table below gives the percent of children under five considered to be underweight.
Percent of Underweight Children Number of Countries
16–21.45 21
21.45–26.9 4
26.9–32.35 9
32.35–37.8 8
37.8–43.25 7
43.25–48.7 2
What is the best estimate for the mean percentage of underweight children? (Round your answer to two decimal places.)
The best estimate for the mean percentage of underweight children is of 27.7%.
----------
The best estimate for the mean percentage is found using the sums of the multiplications of the relative frequencies and the halfway point of each interval.In total, there are 21 + 4 + 9 + 8 + 7 + 2 = 51 countries.The halfway points and relative frequencies are:
(21.45 + 16)/2 = 18.725, with a relative frequency of 21/51 = 0.4118,(21.45 + 26.9)/2 = 24.175, with a relative frequency of 4/51 = 0.0784,(26.9 + 32.25)/2 = 29.575, with a relative frequency of 9/51 = 0.1765,(32.35 + 37.8)/2 = 35.075, with a relative frequency of 8/51 = 0.1569,(37.8 + 43.25)/2 = 40.525, with a relative frequency of 7/51 = 0.1373,(43.25 + 48.7)/2 = 45.975, with a relative frequency of 2/51 = 0.0392.----------
The best estimate for the mean percentage is:
\(p = 18.725(0.4118) + 24.175(0.0784) + 29.575(0.1765) + 35.075(0.1569) + 40.525(0.1373) + 45.975(0.0392) = 27.7\)

what is the vertex of x^2 + 4x - 12
Answer:
\((-2, -16)\\\)
Explanation:
The vertex of a quadratic function which gets plotted as a parabola is either the minimum or maximum (x, y) value of that function.
The following rule applies to finding the x value of the vertex
\(\mathrm{The\:vertex\:of\:an\:up-down\:facing\:parabola\:of\:the\:form}\:\\y=ax^2+bx+c\:\mathrm{is}\:x_v=-\dfrac{b}{2a}\)
The equation is
\(y=x^2+4x-12\)
\(\textrm {Here }\\a = 1, b = 4, c= -12\\\\\)
\(So\; x_v, \textrm{ the x value of the vertex } = -\dfrac{4}{2\cdot \:1} = -2\\\\\textrm {Plug this value of x into the equation to find the y-value of the vertex}\\\)
\(y_v=\left(-2\right)^2+4\left(-2\right)-12\\\\\\y_v = 4 -8 - 12 = -16\\\\\)
\(\mathrm{Therefore\:the\:parabola\:vertex\:is}\\(-2, -16)\)

Based on the calculations, the IQR of this data is equal to 2.
How to determine the IQR of this data?IQR is an acronym for interquartile range and it is a measure of the middle 50% of data values when they are ordered from lowest to highest.
Next, we would order the data from lowest to highest and then determine the median as follows:
Data = {1, 4, 4,} 4, {4, 6, 5}
Median = 4.
For Q₁ of the lower half of the data, we have:
Lower half = {1, 4, 4,}
Q₁ = 4.
For Q₃ of the upper half of the data, we have:
Upper half = {4, 6, 5}
Q₃ = 6.
Mathematically, IQR is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):
IQR = Q₃ - Q₁
IQR = 6 - 4
IQR = 2.

[D] The biggest problems for the environment are caused by humans.
The author's perspective in "Human Impact on our Environment" can be identified as D) The biggest problems for the environment are caused by humans.
This perspective implies that human activities have a significant and detrimental effect on the environment.
It suggests that humans, through their actions and behaviors, are the primary cause of environmental issues and challenges we face today.
The author likely believes that factors such as pollution, deforestation, habitat destruction, overconsumption, and climate change are predominantly driven by human actions.
This perspective aligns with scientific consensus and extensive research on the topic.
Numerous studies have shown that human activities, particularly industrialization and unsustainable practices, have led to a range of environmental problems.
These problems include air and water pollution, loss of biodiversity, habitat degradation, and climate change.
By emphasizing the impact of human actions on the environment, the author likely aims to raise awareness and promote a sense of responsibility for addressing these issues.
It suggests that changes in human behavior, policy interventions, and sustainable practices are necessary to mitigate and reverse the negative effects on the environment.

You are asked to improve a test measuring a construct of your choice. First, identify the construct the test is measuring. Then, describe what you would do to improve the test and why. What method of estimating reliability would you use for your test and why? (Note: not every reliability method is appropriate for every type of test!)
Please come up with three examples of what you believe has caused past errors in your test score. Next, classify each source of error as a method error or trait error, and whether or not you believe this had a negative or positive effect on the obtained score
I need at least one outside reference.
The examples of construct that the research test can be measuring include:
How often does one make eye contact with others?Do you prefer having a smaller group of friends or larger group?What is construct validity?It should be noted that construct validity simply means the extent to which a test accurately assesses what it's meant to assess.
The way to improve the test is to ensure that the measurements and indicators are carefully developed based on the existing knowledge.
The method of estimating reliability that would be used for the test is the split-half method. This is important as it assesses the internal consistency of a test.
The examples of error that can be witnessed on the test include procedural error, environmental error, and human error.
Lastly, trait error is the error that is attributed to the individual which brings about the difference between the true and observed scores while method error is the error that occurs in measurement such that the value obtained is different from the actual value.
