QUESTION:
A chemist wishes to estimate the concentration of particles in a certain suspension. She withdraws 3 mL of the suspension and counts 48 particles. Estimate the concentration in particles per mL and find the uncertainty in the estimate.
ANSWER:Solution
Step 1 of 2
Here we have to estimate the no. of particles in a certain suspension and uncertainty in the estimate
Let X represents the no. of particles in 3 ml of suspension
Let represents the true no.of particles in one ml
Then XPoisson(3)
