Heights of adult males are known to have a normal distribution A researcher claims to have randomly selected adult males and measured their heights with the resulting relative frequency distribution as shown here Identify two major flaws with these results Select all that apply Height cm 130 144 145 159 160 174 175 189 190 204 Relative Frequency 23 25 22 28 29 CHE A The sum of the relative frequencies is 127 but it should be 100 with a small possible round off error B The relative frequencies were recorded as percents instead of counts C The classes do not allow for the possibility that an adult male could be between 144 cm and 145 cm tall or between 159 cm and 160 cm tal D The classes do not allow for the possibility that an adult male could be less than 130 cm tall or greater than 204 cm tall E All of the relative frequencies are different If they are from a normal distribution they should all be exactly the same F All of the relative frequencies appear to be roughly the same If they are from a normal distribution they should start low reach a maximum decrease
