Igor's taxable income is the difference between the amount

he earns annually and the amount he earns as exemptions.

Response:

The amount he pays in annual state income tax is;<u> $1,497</u>

<h3>Which methods are used to calculate income tax?</h3>

Given;

Annual earnings = $57,900

State tax rate = 3%

Amount earned in exemption = $8,000

Required:

The amount Igor pays in annual state income tax.

Solution;

Taxable Income = Annual Income - Exemptions

Therefore;

Igor's taxable income = $57,900 - $8,000 = $49,900

Taxable Income × Tax rate = Amount paid as tax

The amount he pays is therefore; $49,900 × 3% = <u>$1,497</u>

Researchers are interested if a school breakfast program leads to taller children. Assume that the population of all 5 year-old

DedPeter [7]

Answer:

$39-1.96\frac{1}{\sqrt{25}}=38.608$

$39+1.96\frac{1}{\sqrt{25}}=39.392$

So on this case the 95% confidence interval would be given by (38.608;39.392)

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X=39$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

$\sigma=1$ represent the population standard deviation

n=25 represent the sample size

Solution to the problem

The confidence interval for the mean is given by the following formula:

$\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (1)

The margin of error is given by:

$ME= z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and we can use excel, a calculator or a tabel to find the critical value. The excel command would be: "=-NORM.INV(0.025,0,1)".And we see that $z_{\alpha/2}=1.96$
