Yeast cells are suspended in a liquid medium. A 2 mL sample of the suspension is withdrawn. A total of 56 yeast cells are counted. a) Estimate the concentration of yeast cells per mL of suspension, and find the uncertainty. b) What volume of suspension must be withdrawn to reduce the uncertainty to 1 cell per mL?
