Since the median and mode are to the left of the mean, we conclude that the measurements are skewed to the right. The dotplot shown below confirms this conclusion. Since this is the highest frequency of occurrence for the data set, we say that the set is bimodal with modes at 5 and 6. The distribution should be slightly skewed to the right.

Notice that the mean falls slightly to the right of the median and mode, indicating that the measurements are slightly skewed to the right. It is skewed to the right. The researcher is referring to the average number of children per family calculated for all families in the United States during the s.

The average does not necessarily have to be integer-valued. The mean is 0. The position of the median is 0. Hence, the median salary would be a better measure of center than the mean.

The distribution is skewed to the right. The results of parts a and b are identical. The results should agree with Exercise 2. Then 2 2 2 2 Thus, the proportion of measurements between 30 and 60 is 0. Therefore, the proportion that are greater than 60 must be 0. Note however the gap in the center of the distribution and the two measurements in the upper tail. This is caused by the lack of mounding indicated by the gap in the center of the distribution. The second set has a slightly higher location and spread.

Then 0. Using the range approximation, 4 9 4 2. The intervals, counts and percentages are shown in the table. This is because the shape of the distribution is not mound-shaped, but flat. The distribution will probably be skewed right.

Therefore, the approximate values given by the Empirical Rule are not accurate, indicating that the distribution cannot be mound-shaped. The tally and the relative frequency histogram follow. Then 7. Note that the Empirical Rule should be fairly accurate, as indicated by the mound- shape of the histogram in part a. Then 2 2 2 2 , 30 This is because the distribution is not quite mound-shaped. A typical histogram is shown below. Note that the Empirical Rule is not very accurate for the first interval, since the histogram in part a is skewed.

A typical stem and leaf plot is generated by Minitab. Then Then 21 1. Then, 79 4. Find the positions of the quartiles, and the measurements that are just above and below those positions.

Then find the quartiles by interpolation. The lower quartile is in position 0. Hence, 15 6 2 5. Then 57 4. The positions of the quartiles are 0.

The lower and upper fences are: 1 3 1. The box plot is shown below. Then the lower and upper fences are: 1 3 1. Since there are no outliers, the whiskers connect the box to the minimum and maximum values in the ordered set. Mercury c-d The boxplot does not identify any of the measurements as outliers, mainly because the large variation in the measurements cause the IQR to be large.

However, the student should notice the extreme difference in the magnitude of the first four observations taken on young dolphins. These animals have not been alive long enough to accumulate a large amount of mercury in their bodies. Weight 1. The sorted measurements are shown below.

For Peyton Manning, 22 25 2 For Peyton Manning, calculate 3 1 The box plots are shown below. Manning Favre Completed Passes c Answers will vary. The Favre distribution is relatively symmetric except for the one outlier; the Manning distribution is roughly symmetric, probably mound-shaped. The Manning distribution is slightly more variable; Manning has a higher median number of completed passes.

The distribution is skewed to the right with three outliers Truman, Cleveland and F. The box plot is shown on the next page. The mean is There are no outliers. The long left whisker and the median line located to the right of the center of the box indicates that the distribution that is skewed to the left. The student should notice the outliers in the female group, and that the median female temperature is higher than the median male temperature.

Raisins Generic Sunmaid d If the boxes are not being underfilled, the average size of the raisins is roughly the same for the two brands. However, since the number of raisins is more variable for the Sunmaid brand, it would appear that some of the Sunmaid raisins are large while others are small. The individual sizes of the generic raisins are not as variable.

Using the range approximation, 4 14 4 3. This is close to the percentage given by the Empirical Rule. Therefore the range is Then 2 2 2 Since At least 0 fall in the first interval, at least 3 4 0. The data distribution does not have a strong mound-shape see the relative frequency histogram in the solution to Exercise 1.

There is one outlier, TIME Prices 2.
