Unaltered bitumens, as commonly found in leadzinc deposits, have atomic hydrogen/carbon
Chapter 7, Problem 7.54(choose chapter or problem)
Unaltered bitumens, as commonly found in leadzinc deposits, have atomic hydrogen/carbon (H/C) ratios that average 1.4 with standard deviation .05. Find the probability that the average H/C ratio is less than 1.3 if we randomly select 25 bitumen samples.
