• the magnitude, m, of an earthquake is defined to be m = log startfraction i over s endfraction, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. which equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake? m = log startfraction i over s endfraction m = log (10 s) m = log startfraction 10 s over s endfraction m = log startfraction 10 over s endfraction

• a driver's education course compared 1,500 students who had not taken the course with 1,850 students who had. of those students who did not take the driver's education course, 1,150 passed the written driver's exam the first time compared with 1,440 of the students who did take the course. a significance test was conducted to determine whether there is evidence that the students who took the driver's education course were more likely to pass the written driver's exam the first time. what is the p-value for an appropriate hypothesis test?

• graph a: a uniform density curve is at y = one-fourth from negative 1 to 3. graph b: a line goes from (negative 1, 0) to (0, one-third), is horizontal to (2, one-third), and then decreases to (3, 0). which graph represents a density curve, and why? graph a only, because the curve is above the horizontal axis, and the area under the curve is 1 graph b only, because the curve is above the horizontal axis, and the area under the curve is 1 both graph a and graph b, because both curves are above the horizontal axis, and the areas under both curves equal 1 neither graph a nor graph b, because, even though both curves are above the horizontal axis, the area cannot be determined for graph b
