A group conducted a study of the calorie content of different types of beer. The calorie content (calories per 100 ml) for 26 brands of light beer are summarized in the table below. 43 39 25 35 34 19 37 41 30 38 31 27 33 41 39 29 22 41 27 28 39 24 22 36 37 35 (a) Construct a stem-and-leaf display using stems 1, 2, 3, and 4. (Enter numbers from smallest to largest separated by spaces. Enter NONE for stems with no values.) Calorie Content 1 2 3 4 Stem: Tens Leaf: Ones (b) Describe the calorie content of light beers. (Select all that apply.) There are no gaps in the data. A typical calorie content is 40 calories per 100 ml. There is a large gap in the data. A typical calorie content is 33 calories per 100 ml. The distribution is negatively skewed, with one peak. The distribution is roughly symmetric. The distribution is positively skewed, with one peak.
15. Diameter of Douglas Fir Trees The diameter of the Douglas fir tree is measured at a height of 1.37 meters. The S following data represent the diameter in centimeters of a random sample of 12 Douglas firs in the western Washington Cascades. 156 162 147 173 147 190 130 101 159 113 181 109 Source: L. Winter. "Live Tree and Tree-Ring Records to Reconstruct the Structural Development of an Old-Growth Douglas Fir/Western Hemlock Stand in the Western Washington Cascades." Corvallis, OR: Forest Science Data Bank, 2005. (a) Obtain a point estimate for the mean and standard deviation diameter of a Douglas fir tree in the western Washington Cascades. (b) Because the sample size is small, we must verify that the data come from a population that is normally distributed and that the data do not contain any outliers. The figures show the normal probability plot and boxplot. The correlation between the tree diameters and expected z-scores is 0.982. Use Option 1 or Option 2 to determine if the…
Is there a relation between murder and arson? A random sample of 15 Midwest cities (over 10,000 population) gave the following information about an annual number of murder and arson cases.

Find the minimum and maximum of the data. 1. Create a stemplot of the data. 2. Organize the stems of the stemplot. 3. Create a new stemplot by splitting the stems. 4. Make a frequency table of the data, with a first interval of “19-22": 5. Create a histogram of the data from the frequency table. 6. Check your work by replicating the histogram on your calculator.

Recall that we previously calculated x⎯⎯x¯ = 42.95 and s = 2.6424 for the 65 ratings. Use the Empirical Rule to create the intervals. (Round your expected frequencies to 2 decimal places. Round your answer to 3 decimal places.)
