The underlined numerical value 8% is a parameter because the data set of all 843 animals in a zoo is a population.

Option B is correct.

<h3>What is the difference between a parameter and a statistic?</h3>

In quantitative research, numerical data are gathered and analyzed to identify patterns, identify relationships, or test hypotheses.

A statistic is a number that describes a sample i.e. sample mean, whereas a parameter is a number that describes the entire population (such as the population mean). Identifying the population parameters helps quantitative research understand population patterns.

From the given information:

The underlined numerical value is a parameter. This is because the data set of all 843 animals in a zoo is a population.

It implies that:

  • The total population of all animals in the Zoo = 843
  • The proportion = 8%

Thus, it is the ratio concerning the population. As such, 8% is population proportion(Parameter).

Answer:

424 cm²

Step-by-step explanation:

The figure is composed of a square and a trapezium on top

A of square = 18² = 324 cm²

A of trapezium = \frac{1}{2} h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 8, b₁ = 18 and b₂ = 7 , then

A = 0.5 × 8 × (18 + 7) = 4 × 25 = 100 cm²

Area of hexagonal park = 324 + 100 = 424 cm²

Eddi Din [679]

Answer:

x ≥ 12

y ≤ 25 - x

Step-by-step explanation:

Given:

Number of total members = 25

Number of at least male members = more than 12

Find:

Inequality

Computation:

Assume number of female members = y

So,

x ≥ 12

And

y ≤ 25 - x
