Question

When one is constructing a table representing the frequency distribution of weight (lb) of discarded textile items from Data Set 23 in Appendix B, the first two classes of a frequency distribution are 0.000-0.99 and -1.99 What is the class width? Using the same first two classes from Exercise 1 identify the class boundaries of the first class. The first class described in Exercise 1 has a frequency of 51. If you know only the class limits given in Exercise 1 and the frequency of 51 can you identify the original 51 data values? A stemplot is created from the intervals (min) between eruptions of the Old Faithful geyser in Yellowstone National Park, and one row of that stemplot is 6|1222279. Identify the value represented by that row. In the California Daily 4 lottery, four digits between 0 and 9 inclusive are randomly selected each day. We normally expect that each of the ten different digits will occur about 1/10 of the time, and an analysis of last year's results shown that this did happen. Because the results are what we normally expect, is it correct to say that the distribution of selected digits is a normal distribution? In an investigation of the travel costs of college students, which of the following does not belong: center: variation: distribution: bar graph: outliers: changing patterns over time? In an investigation of the relationship between SAT scores and grade point averages(GPA) of college students, which of the following graphs is most helpful: histogram: pie chart: scatterplot: stemplot: dotplot? As a quality control manager at Sony, you find that defective CD's have various causes, including worn machinery, human error, bad supplies, and packaging mistreatment, Which of the following graphs is most helpful: histogram: pie chart: scatterplot: Pareto chart: dotplot: pie chart? What characteristic of a data set can be better understood by constructing a histogram? A histogram is to be constructed from the brain sizes listed in Data Set 6 of Appendix B. Without actually constructing that histogram, simply identify two key features of the histogram that would suggest that the data have a normal distribution.

Explanation / Answer

4) A stemplot is created from the inerval hence the values in the row 6|1222279 will be as

a) 61 b) 62 c) 62 d) 62 e) 62 f) 67 g) 67

6) in Inestigation of travel cost their will be bar-graph and outlier are not to be obtained.

7) histogram and Scatter Diagrame

8) Pie- Chart and Histogram

9) The characteristic of data set can be better understood by constructing histogram will be, from the histogram

we conclude that data have some type of distribution and which is understand by shape of histogram or ogive curve.
