gladu [14]3 years ago
4 0

Answer:

55%

Step-by-step explanation:

Make 11 out of 20 as a fraction:

\frac{11}{20}

11 ÷ 20 is 0.55.

To make a decimal a percent, you multiply it by 100. So,

0.55 x 100 = 55

                  = 55%

So, the answer is 55%

Randy is starting a beehive so that he can have fresh honey. He decides to check the current population of bees in the hive by m
satela [25.4K]

Answer:

Best estimate for the bee population is 1280.

Step-by-step explanation:

Randy marked total number of bees = 160

Then he collected 240 bees and observed that number of bees marked

= 30

We have to find the total population of the bee or best estimate for the bee population.

Now we use the ratio of marked bees in the sample vs marked bees in the total population

\frac{\text{Number of bees marked in the sample}}{\text{Total bees in the sample taken}}=\frac{\text{Number of bees marked in total population}}{\text{Number of bees in the hive}}\frac{30}{240}=\frac{160}{x}

x = \frac{160\times 240}{30}=1280

Therefore, the best estimate for the bee population is 1280.

Sauron [17]

Answer:

D) college students

The college students are best describes the population

Step-by-step explanation:

<u>Explanation</u>:-

<u>Introduction</u>:-

The outcome of a statistical experiment may be recorded either as a numerical value or as a descriptive representation.

<u>Example</u>:-

  • when a pair of dice are tossed and the sum of the numbers on the faces is the outcome of interest, we record a numerical value.
  • If the students of a certain school are given blood tests and the type of blood is of interest, we record a numerical value.

In particular study, the number of possible observations may be <u>small, large but finite or infinite.</u>

<u> Example :- 1</u>

In the classification of blood types we can only have as many observations as there are students in the school.

Therefore the results are <u>finite number</u> of observations.

<u>Example :- 2</u>

If we could toss a pair of dice indefinitely and record the sums occur, we would obtain an infinite set of values .

<u>Population</u>:-

The total of observations which we are concerned , whether this number is finite or infinite , this is called the<u> population</u>

The number of observations in the population is defined to be the size of the population.

<u>Example</u> :- If there are 600 students in the school that we classified according to blood group, we say that the population of size is 600.

<u>Sample</u>:- A sample is subset of a population

Therefore in given data

The college students are best describes the population

Female college students , part -time college students , and female part-time college students are samples it will come from population
