4. Which population distribution is more likely to be well represented by a very small sample? 100 25 44 75 50 25 10 20 30 40 50 100 30.79 75 50 25 10 20 30 40 50 O A The top (red) distribution would be better represented by a small sample because it is more spread out. O B. The bottom (blue) distribution would be better represented by a small sample because it is less spread out OC. There should be no difference as long as the samples are randomly selected. O D. The two cannot be compared because their means are different.

- Suppose your dependent variable is crime rates for various cities. To correct for heteroskedasticity you should Select one: a. multiply observations by the city size b. multiply observations by the square root of the city size c. none of these d. divide observations by the square root of the city size e. divide observations by the city sizeSuppose your dependent variable is aggregate household demand for electricity for various cities. To correct for heteroskedasticity you should Select one: a. multiply observations by the square root of the city size b. multiply observations by the city size c. divide observations by the city size d. divide observations by the square root of the city size e. none of theseA city's transportation committee has conducted research on traffic and car accidents for downtown streets. There is a 9% chance of being involved in a car accident when 15 or more cars are driving on Johnson Street and a 7.5% chance when 20 or more cars are driving on Dublin Street. The two streets intersect to form a risk area with a radius of 0.1 mi. Approximate the density of cars per square mile in the risk area when 17 cars are on Johnson Street and 21 cars are on Dublin Street. Use 3.14 for pi. There are approximately 1,210 cars per square mile in the risk area. There are approximately 2,674 cars per square mile in the risk area. There are approximately 2,165 cars per square mile in the risk area. There are approximately 1,082 cars per square mile in the risk area.

- An industrial concern has experimented with several different mixtures of the fourcomponents—magnesium, sodium nitrate, strontium nitrate, and a binder—that comprise arocket propellant. The company has found that two mixtures, in particular, give higher flare illumination values than the others. Mixture 1 consists of a blend composed of the proportions.40, .10, .42, and .08, respectively, for the four components of the mixture; mixture 2 consists ofa blend using the proportions .60, .25, .10, and .05. Twenty different blends (10 of each mixture)are prepared and tested to obtain the flare-illumination values. These data appear here (in unitsof 1,000 candles).Mixture 1 185 192 201 215 170 190 175 172 198 202Mixture 2 221 210 215 202 204 196 225 230 214 217a. Plot the sample data.

The younger Neotropical termites secrete a liquid that lacks the blue component, so it is white in appearance. In an experiment that measured the toxicity of the blue substance, the researchers placed one drop of either the blue liquid or the white liquid on individuals of a second termite species, Labiotermes labralis. Of the 41 Labiotermes labralis that got the blue drop, 37 were immobilized. Of the 40 Labiotermes labralis that got the white drop, 9 were immobilized. Is the blue liquid toxic compared to the white liquid?
