pychu [463]

Answer:

Standard error of the mean parameter the average content of colognes

                                S.E = 0.02 ounces                            

Step-by-step explanation:

<u><em>Explanation</em></u><em>:-</em>

<em>Size of random sample 'n' = 121 bottles</em>

<em>mean of the sample </em>x^{-} = 4 ounces

<em>Standard deviation of Population</em>

<em>                       σ = 0.22</em>

<em>Standard error of the mean parameter the average content of colognes</em>

<em>                              </em>S.E = \frac{S.D}{\sqrt{n} }<em></em>

<em>                              </em>S.E = \frac{S.D}{\sqrt{n} } = \frac{0.22}{\sqrt{121} }<em></em>

                             S.E = 0.02

<u><em>Final answer:-</em></u>

<em> Standard error of the mean parameter the average content of colognes</em>

<em>                S.E = 0.02 ounces                            </em>

The Roosevelt’s and the jaspers live in the same city and pay the same sales tax rate, and both families made 16,000 in taxable
HACTEHA [7]

Answer:

Yes, the sales tax in their city is an example of regressive tax

Step-by-step explanation:

Firstly, we need to understand what is meant by the term regressive tax.

What is meant by a regressive tax system is a system of taxation in which there is a decrease in tax rate as there is an increase in amount subjected to tax.

Now, the key to knowing if what we have in the question is a regressive taxation is by calculating the percentage of the tax that was paid.

For the Roosevelt’s , the percentage of tax paid would be 16,000/91,000 * 100% = 17.6%

For the Jasper’s, the percentage of tax paid would be 16,000/37,000 * 100% = 43.24%

We can see that at a lower amount subjected to tax, the Jasper’s paid more and thus we can conclude irrevocably that sales tax in their city is an example of a regressive tax
