Chapter 3: Q 3.85. (page 115)

In each Exercises 3.82-3.90, use the technology of your choice to determine and interpret the range and sample standard deviation for those data sets to which those concepts apply. If those concepts don't apply, explain why. Note: If an exercise contains more than one data set, perform the aforementioned tasks for each data set.

Ballot Preferences. In Issue 338 of the Amstat News, then president of the American Statistical Association, F. Scheuren reported the results of a survey on how members would prefer to receive ballots in annual elections. On the WeissStats site, you will find data for preference and highest degree obtained for the 566 respondents.

Short Answer

Expert verified

The range and standard deviation for the given data can not be found.

Step by step solution

01

Step 1. Given information.

The given statement is:

The survey is conducted on how members would like ballots for yearly elections to be delivered.

02

Step 2. Determine the data's range and standard deviation.

Range=max-min

s=鈭�xi2-鈭�xi2/nn-1

The categories will include the Ballot preferences in annual elections, it is a qualitative variable.

Finding the range and standard deviation is not possible for this data.

And to be able to find the range and standard deviation require numerical data, and hence a quantitative variable, for the provided data set.

Copperhead and Tiger Snakes. S. Fearn et al. compare two types of snakes in the article 鈥淏ody Size and Trophic Divergence of Two Large Sympatric Elapic Snakes in Tasmania鈥� (Australian Journal of Zoology, Vol. 60, No. 3, pp. 159-165). Tiger snakes and lowland copperheads are both large snakes confined to the cooler parts of Tasmania. The weights of the male lowland copperhead in Tasmania have a mean of 812.07 g and a standard deviation of 330.24 g; the weights of the male tiger snake in Tasmania have a mean of 743.65 g and a standard deviation of 336.36 g.
a. Determine the z-scores for both a male lowland copperhead snake and a male tiger snake whose weights are 850 g.
b. Under what conditions would it be reasonable to use z-scores to compare the relative standings of the weights of the two snakes?
c. Assuming that a comparison using z-scores is legitimate, relative to the other snakes of its type, which snake is heavier?

Specify the mathematical symbol used for each of the following descriptive measures. a. Sample mean b. Sample standard deviation c. Population mean d. Population standard deviation.

The Beatles. In the article. "Length of The Beatles' Songs",(Chance Vol. 25. No. 1, pp. 30-33). T. Koyama discusses aspects and interpretations of the lengths of songs by The Beatles. Data on the length, in seconds, of 229 Beatles' songs are presented on the Weiss Stats site.
