The number of bacterial colonies on a petri dish can has an average of 2.5 per cm2 . i. Define the variable of interest for this scenario. ii. What probability distribution do you think best describes the situation? Why? iii. Calculate the mean and standard deviation of the distribution iv. Find the probability that a) in 1 cm2 there are no bacterial colonies b) in 4 cm2 there are more than three bacterial colonies.
