Also need help getting tar (mg) in filtered cigarettes frequency for 23-27, 28-32, 33-37.
Construct one table that includes relative frequencies based on the frequency distributions shownbelow, then compare the amounts of tar in nonfiltered and filtered cigarettes. Do the cigarette filters appear to beeffective? (Hint: The filters reduce the amount of tar ingested by thesmoker.)

Explanation / Answer
If any of the classes aren't there then that simply means that the frequency corresponds to that class is 0.
Hence,
The relative frequencies will be:
Tar (mg) Non-flitered Flitered 3-7 (0/25)*100 = 0% (3/25)*100 = 12% 8-12 0% 12% 13-17 8% 20% 18-22 0% 56% 23-27 52% 0% 28-32 24% 0% 33-37 16% 0%Related Questions
