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.

(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.
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.

We discuss how to test for an association between two categorical variables in Section 6.8. A marine research team records the number of fish from 3 species that they find at different depth categories in the ocean. They are interested in assessing whether or not there is a relationship between the depth category (close to surface, mid-level, ocean floor) and the fish species found (species A, species B, species C). A two-way table showing the classification of a sample of 150 observations is given below. If the variables for the ocean depth category and the species are independent, how would you calculate the expected number of fish that are at the mid-level and from species C? Expected number =

1. A researcher wishes to determine if the following distances (in meters) traveled by a random sample of ten world-class long jumpers are highly affected by the speed (in meters per second) at takeoff. The distances recorded from the sample long jumpers are as follows: 7.67, 8.22, 7.94, 7.16, 8.08, 7.35, 7.89, 7.76, 7.25, and 7.43. On the other hand, the speeds are recorded as follows: 8.9, 9.2, 8.1, 8.6, 9.0, 8.4, 8.8, 9.1, 8.0, and 8.2. What will be the distance, assuming that the speed is 9.4 meters per second? Round your answer to two decimal places. There is no need to place the unit. 2. A certain regression line equation has the slope equal to 720.25 and an intercept that is equal to -182.4. What will be the predicted score for the dependent variable if the independent variable is 281.5? Round your answers to two decimal places. Do not place any unit.
