Consider the RVP data presented in Table 15.3. Using the RSS approach discussed in Example 15.1 with set size k = 2, how many of the 36 samples obtained from the pump would we have needed to send to the laboratory for more formal RVP measurements?
Example 15.1
Unburned hydrocarbons emitted from automobile tailpipes and via evaporation from manifolds are among the primary contributors to ground-level ozone and smog levels in large cities. One way to reduce the effect of this factor on air pollution is through the use of reformulated gasoline, designed to reduce its volatility, as measured by the Reid Vapor Pressure (RVP) value. To assure that gasoline stations in metropolitan areas are selling gasoline that complies with clean air regulations, regular samples of reformulated gasoline from the pumps at these stations are collected and RVP values are measured.
