Answers

Answer 1

As per the combination method, there are 42504 different campout crews are possible.

Combination method:

In math, combination method means a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Given,

Scout troop 456 has 24 members. the scoutmaster appoints a 5-member campout crew composed of a leader, a cook, and a cleanup crew (3 scouts).

Here we need to find the number of different campout crews are possible.

According to the nCr formula, here the value of

n = 24

And the value of r = 5

Then the number of possible combinations are calculated as,

=> ²⁴C₅ = 24!/5!(24 - 5)!

=> ²⁴C₅ = 24!/5!19!

=> ²⁴C₅ = 42504

Why do we take the square root of the mean squared error to calculate the root mean squared error?.

Answers

The square in RMSE is utilized because it consistently provides a positive number for error, preventing errors from canceling one another out, and grants higher weight to values further from the target function, emphasizing locations for which the estimator is unreliable. To reverse the results of squaring, use the square root. 

What is RMSE?

The difference between values (sample or population values) predicted by a model or estimator and the values observed is typically measured using the root-mean-square deviation (RMSD) or root-mean-square error (RMSE).

The RMSD is the quadratic mean of the square root of the second sample moment of the discrepancies between expected values and observed values.

When computations are made outside of the data sample that was used for estimation, the deviations are referred to as errors (or prediction errors) instead of residuals.

The RMSD is used to combine the sizes of predictions' mistakes for different data points into a single indicator of predictive power. .

RMSD is a metric for accuracy that is used to compare the predicting mistakes of various models.

Hence, The square in RMSE is utilized because it consistently provides a positive number for error, preventing errors from canceling one another out, and grants higher weight to values further from the target function, emphasizing locations for which the estimator is unreliable.

Define the term sample space?A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space. Events are the subset among possible experiment results. Depending on the experiment, a sample area could contain a variety of results.

for the stated question-

Total times the dice is thrown = 3.

Total number of sample space = 6 x 6 x 6 = 216.

The probability of coming six = 1/6

The probability of not coming six = 1 - 1/6 = 5/6.

Probability of getting 6 in third throw = 5/6 x 5/6 x 1/6

a woman decides to purchase a $23,800 car and makes a down payment of $3,500. she arranges to borrow the remainder from a bank that will charge her 4.5% interest. she will make monthly payments for 4 years. a. find her monthly payment amount.

Answers

The monthly payment amount a woman has to pay for the car is $462.91.

Here we have to find the monthly payment amount.

The cost of car = $23,800

Down payment = $3,500

Rate(r) = 4.5%

time(t) = 4 years

Periodic interest(i) = 0.045/12

Formula to calculate monthly payment:

A = P i( 1 + i[tex])^{n}[/tex] / ( 1 + i[tex])^{n}[/tex] - 1

Loan amount = 23800 - 3500

                      = $ 20300

A = 20300 ( 0.045 /12 ( 1 + 0.045/12[tex])^{48}[/tex])/ (1 + 0.045/12[tex])^{48}[/tex] - 1

  = 20300× 0.004488 / 0.196814

  = 462.91

Therefore the monthly payment is $462.91.

What is the percentage?

Percentage means one part of every cent or hundred. And it is represented by symbol '%'.

Given that Ron earns $450 in gross wages on January 10.

To find deduction amount from Ron’s gross wages for social security at 6.2% ;

Firstly, we find  6.2% of $450 that is $450 x 6.2 / 100 = $27.9 and then we substract to the gross wages.

$450 - $27.9 = $422.1

Now to find 1.5 % of $450 that is 450 x 1.5/ 100 = $6.75 and then we substract to the gross wages.

$450 - $6.75 = $443.25

total deduction amount is $6.75 + $27.9 = $34.65

assuming the population standated deviation is known, which of the following statements is true about the standard deviation of the sample mean x

Answers

Assuming the population standard deviation is known and the standard deviation of the sample mean x : option (b) is correct : the standard error of the sample mean decreases.

Central Limit theory:

In probability theory, the central limit theorem (CLT) states that the distribution of a sample variable approximates a normal distribution (i.e., a “bell curve”) as the sample size becomes larger, assuming that all samples are identical in size, and regardless of the population's actual distribution shape.

Standard deviation:

Standard deviation is a calculation of the dispersion or variation in a set of numbers. If the standard deviation is a small number, it means the data points are close to their average value. If the deviation is large, it means the numbers are spread out, further from the mean or average.

There are different ways to write out the steps of the population standard deviation calculation into an equation. A common equation is:

                          σ = ([Σ(x - u)2]/N)1/2

Where:

σ is the population standard deviation

Σ represents the sum or total from 1 to N

x is an individual value

u is the average of the population

N is the total number of the population

a) The probability that a sample of taxpayers from this income group who have itemized deductions will show a sample mean within $210 of the population mean is 0.9482.

b) When trying to estimate the population mean, a greater sample size offers the benefit of improving the estimation's accuracy.

a. The z-score is calculated as follows:

z = (x - μ) ÷ (σ ÷ √n)

Where the sample size is n, the sample mean is x, the population mean is y, and the population standard deviation is z.

By entering the specified values, we obtain:

n = 30: z = (x - 17,545) ÷ (2,160 ÷ √30) = (x - 17,545) ÷ 216

n = 50: z = (x - 17,545) ÷ (2,160 ÷ √50) = (x - 17,545) ÷ 174

n = 100: z = (x - 17,545) ÷ (2,160 ÷ √100) = (x - 17,545) ÷ 132

n = 400: z = (x - 17,545) ÷ (2,160 ÷ √400) = (x - 17,545) ÷ 53

To find the odds that a sampling distribution could be within $210 of both population mean and the z-score, we must first figure out the likelihood that now the z-score would be within 1.96 standard deviations of the mean. This is because the 95th percentile, or the number under which 95% of the data lies, is represented by the z-score of 1.96, which is the value in this case.

To ascertain the likelihood, we must attempt searching up the z-scores in a z-table and get the pertinent probabilities. A z-table is a table that lists the probability associated with various z-scores.

Using the z-scores we used to develop the concept, we could look up the alternatives in a z-table and find the following probability:

n = 30: 0.4056

n = 50: 0.5082

n = 100: 0.6690

n = 400: 0.9482

For each of the aforementioned sample sizes, the likelihood that a sampling of taxpayers from this income category who itemized deductions will exhibit a sample mean that is within $210 of the population mean is:

n = 30: 0.4056

n = 50: 0.5082

n = 100: 0.6690

n = 400: 0.9482

b. The likelihood that the sample means will closely match the true population mean is thereby increased.

The standard deviation averages commonly fall as the sample size rises. In other words, as the sample mean becomes less likely to depart from the actual population mean, the likelihood that the random variable will be close to the population mean increases.

For instance, in the aforementioned case, the likelihood that they would give it a shot would be within 210 of a population mean would rise from 0.4056 for a random sample of just 30 to 0.9482 for a random sample of 400.

This means that the likelihood that they give it a chance will fall within the allowed range of the sample % likewise increases as the sample size increases.
