Rhonda manages wildlife samples for Ducks Unlimited. Two samples of duck populations at a migratory site are shown in the table

below. Which statement about the samples is true?
A. Rhonda needs to continue taking samples of ducks until both samples have at least one of each type of duck.

B. Rhonda should take a third sample and then use the two that are most representative since these samples vary quite a bit.

C. Rhonda should use both of these samples as they are to make inferences about the average population of each type of duck in the pond.

D. Both samples must be biased because there are more Mallards than any other type of duck recorded in the sample.

The statement about the given table above is true is that Rhonda should use both of these samples as they are to make inferences about the average population of each type of duck in the pond. The answer is letter C. Because both ponds are located far away form each other and the gathered sample is enough to explain the population of the different kinds of birds present.

Consider the following population of N = 12 scores:
Goshia [24]

Answer:

Step-by-step explanation:

1. Find the minimun and maximun value of the data.

Minimun: 2

Maximun: 6

2. Calculate the range (R).

Range=

6 - 2=

4

3. Calculate the average.

Average= (Sum of all values) / N

Average= (2+3+3+3+4+4+4+4+5+5+5+6) / 12

Average= (48) / 12

Average= 4.

4. Calculate the M and round the value <u>down</u>.

M=\sqrt{N} =\sqrt{12}=3.46

M= 3

6. Calculate A.

A=\frac{R}{M} =\frac{4}{3} =1.3333

7. Craft your table.

<u>(Check attatched image 1).</u>

LL: Lower limit.

UL: Upper limit.

8. Calculate the limits and fill out the table.

  LL      /      UL

2.00         2.00+A=3.33

3.33          3.3333 +A=4.66    

4.66          5.99

5.99         7.32

7.32         8.65

Filled out table: <u>check attatched image 2.</u>

9. Check the data, count how many values fall into each interval and annotate on "frequency".

For example: There are 4 values between 2 and 3.33, these values are 2,3,3, and 3. Therefore, we write 4 on the frequency (absolute) cell for this row of the table. And we do the same for all the other classes.

<u>Check attatched image 3.</u>

10. Calculate the frequency (relative) for all classes.

For example: the first class (row 1 of the table) contains 4 values. Therefore, it's relative frequency would be:

\frac{4}{N}=\frac{4}{12} =0.3333=33.33%

Note: We divide by 12 b<u>ecause N=12</u>.

Do the same for all the other rows and finish filling out the table.

<u>Check attatched image 4.</u>

<u>-------------------------------------------------------------------------------------------------------</u>

<u>Extra.</u> To make an histogram, take the interval and the absolute frequency and graph it in the fashion shown in attatched image 5.
