The correct option is D.

A. Statistics can be used to organize and analyze information.

B. Statistics involves collecting and summarizing data.

C. Statistics is used to draw conclusions using data.

D. Statistics is used to answer questions with 100% certainty.

As we know Statistics concerns the collection, organization, analysis, interpretation, and presentation of data. So, if we look at the statements:

A. Statistics can be used to organize and analyze information, which is true.

B. Statistics involves collecting and summarizing data, which is true.

C. Statistics is used to draw conclusions using data, which is true.

D. Statistics is used to answer questions with 100% certainty, which is false.

Therefore, all the statements are correct except D.

Hence, the correct option is D.

D. Statistics is used to answer questions with 100% certainty.

Step-by-step explanation:

The statistics refer to the analyses, organizing, presenting, interpreting, collecting, and summarizing the data based on the mathematical models that help you to make the conclusions using the data.

Moreover, it does not give 100% certainty with respect to answering the questions but it provided you an accurate data most of the time.

There are various models like correlation, regression models through we can do the analysis.

Answer from: Quest

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

= $\sqrt{(9-6)^{2} +(12-6)^{2} } \\=\sqrt(45)=3\sqrt(5)$

side j'k'=distance between j' and k'

= $\sqrt{(3-2)^{2} +(2-4)^{2} } \\=sqrt(5)$

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
