Answer: The answer is (c) estimate of a variable, as determined through a sample.

Step-by-step explanation: We are given four different options out of which one gives the perfect definition of a parameter.

In mathematics, a parameter is defined as a constant or a variable in a function that determines a particular form of the function but not its general form. For example, f(x) = k x, where 'k' determines only the gradient of the line described by f(x).

In statistics, a parameter is defined as a variable that enters in the mathematical form of a distribution such that the possible values of the variable correspond to different distributions.

Thus, the correct option is (c) estimate of a variable, as determined through a sample.

Irina-Kira [14]

$ 2772 is paid in state income tax

Solution:

Given that, Tina lives in a state that charges her 4.5% state income tax on her federal taxable income

Federal taxable income = $61,600

To find: Amount paid by Tina in state income tax

Tax rate = 4.5 %

Which means, 4.5 % of $61,600 is paid as tax

$Tax\ Rate = 4.5 \% \text{ of } 61600$

Here, "of" means multiplication or product

$Tax\ Rate = 4.5 \% \times 61600\\\\Tax\ Rate = \frac{4.5}{100} \times 61600\\\\Tax\ Rate = 0.045 \times 61600\\\\Tax\ Rate = 2772$

Thus $ 2772 is paid in state income tax
