A statistical question you can ask at least 20 different people can be: "How many pets do you have?"

An hypothetical data for the number of pets 20 sixth graders have has been given and the box plot that displays the data set is in the image below.

<h3>What is a Statistical Question?</h3>

A statistical question can be defined as a question that can be answered by collecting a variety of numerical answers that vary. Examples of statistical questions include:

  • What are the age of students in my class?
  • What are the heights of students in a class?

A statistical question you can ask at least 20 different people can be: "How many pets do you have?"

Below is the hypothetical questions that can be assumed you'd get from two people:

0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 4, 5, 5

Description of the people you asked can be: 20 sixth graders in your school.

How you gathered your data can be: Asking them to fill a questionnaire or by interview.

The numerical data from least to the greatest, hypothetically would be:

0, 0, 1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 4, 5, 5

The five-number summary for the hypothetical data would be:

Minimum: 0 (least data point)

Quartile Q1: 1 (middle of the first half of the data distribution)

Median: 1.5 (center of the data)

Quartile Q3: 2.75 (middle of the second half of the data distribution)

Maximum: 5 (greatest data value).

Using the five-number summary generated, the box plot that displays the data set is shown in the image attached below.

gregori [183]
Okay so 300 meters per minute and he ran 8 minutes..

300x8=2400

He still had 600 left to go...

2400+600=3,000

He had to run three times longer than Eric...

3000/3=1000

Does that make sense?

A student solving for the acceleration of an object has applied appropriate physics principles and obtained the expression a=a1+
egoroff_w [7]

Answer:

a=\frac{3\times 7}{7}+\frac{12}{7}  (First step for obtaining a common denominator for the two fraction)

a=\frac{33}{7}\text{ m/s}^2

Step-by-step explanation:

\text{Given Expression: }a=a_1+\frac{F}{m}

where,

a is acceleration of an object.(Need to calculate)

a_1=3.00\text{ m/s}^2

F=12.0\text{ Kg.m/s}^2

m=7.00\text{ kg}

\text{Substitute }a_1, \text{ F, and m into expression and we get}

a=3+\frac{12}{7}

Now we will simplify above expression for a

First we make common denominator.

Common denominator is 7. So, we make both denominator 7. We multiply by 7 at top and bottom with 3. We get

a=\frac{3\times 7}{7}+\frac{12}{7}  (First step for obtaining a common denominator for the two fraction)

Now we combine the numerator

a=\frac{21+12}{7}

a=\frac{33}{7}\text{ m/s}^2
