8. Suppose a variable (lambda, pronounced "LAM-da," a lowercase Greek letter commonly used in physics) can attain a value equal to any positive real number. In this instance, is an example of (a) a continuous variable (b) a discrete variable (c) an absolute variable (d) a relative variable 9. The largest cumulative absolute frequency in a set of numbers is equal to (a) the sum of all the individual absolute frequency values (b) twice the mean (c) twice the median (d) twice the mode 10. Which of the following is an expression of the extent to which values are spread out relative to the mean? (a) The average. (b) The mode. (c) The median. (d) None of the above. 11. Empirical probability is based on (a) observation or experimentation (h) theoretical models only (c) continuous outcomes (d) standard deviations 12. Imagine a perfectly balanced spinning wheel, in which the likelihood of the pointer coming to rest within any particular range of directions (shaped like a thin slice of pie) is the same as the likelihood of its coming to rest within any other range of equal size. if the direction in which the pointer comes to rest, measured in degrees of the compass (clockwise from true north), is the random variable, the density function that represents the behavior of this wheel can be described as (a) a discrete distribution (b) a normal distribution (c) a uniform distribution. (d) none of the above
