Inga, Kai, and Jason volunteer in the school library. They want to find the average number of pages of a library book. It would

be unreasonable to calculate the number of pages in every book to find the average. They decide they need to find a valid sample.
Inga suggests choosing 100 books from the history section to get a sample.

Kai suggests randomly selecting 100 books from the library’s entire catalog.

Jason suggests using 100 books from the teen fiction section to get a sample.

Who suggested the best way to produce a random sample that is not biased?

Is 8/9 bigger than 2/3
swat32

Answer:

Yes

Step-by-step explanation:

To get the answer, we first convert each fraction into decimal numbers. We do this by dividing the numerator by the denominator for each fraction as illustrated below:

8/9 = 0.889

2/3 = 0.667

Then, we compare the two decimal numbers to get the answer.

0.889 is greater than 0.667

complete the standard deviation of the following set of data to the nearest whole number: 8, 12, 15, 17, 18​
kogti [31]

Answer:

4

Step-by-step explanation:

1. Find the Mean

(8+12+15+17+18)/5=14

2.For each number, subtract the Mean and square the result.

(8-14)^2=36

(12-14)^2=4

(15-14)^2=1

(17-14)^2=9

(18-14)^2=16

3. Find the Mean of those squared differences.

(36+4+1+9+16)/5=13.2

4.Take the square root of that and this is what you want.

square root of 12.7 = 3.6 (round up to 4)
