Question

Unaltered bitumens, as commonly found in lead-zinc deposits, have atomic hydrogen/carbon (H/C) ratios that average 1.9 with standard deviation 0.05. Use R to find the probability that the average H/C ratio is less than 1.85 if we randomly select 25 bitumen samples. (Round your answer to four decimal places.)

Step 1

9 and the standard deviation is 0.05. We are asked to find the probability that the average H/C ratio is less than 1.85 for a sample of 25 bitumen samples. Show more…
