Final answer:
Without the specific functions for r(x) and p(x) or additional context, it's impossible to determine the range of values for x such that r(x) < p(x).
Step-by-step explanation:
To find the range of values for which r(x) < p(x), a comparison of two functions, we need additional information like the actual functions of r(x) and p(x). The given options suggest an inequality statement that describes a range of values for x. Without the specific functions or additional context, determining the correct range for x such that r(x) < p(x) is not possible. Provided information about the probability P(c < x < d) and data about a normal distribution centering around the mean emphasizes the importance of the context within which these inequalities are used. Similarly, a normal distribution with a mean of -3 and probability areas are given, but without a link to r(x) < p(x), it is not adequate to deduce the correct range for x.
