Final answer:
For a Poisson distribution with λ = 16, both the mean and the standard deviation are 16 and 4, respectively.
Step-by-step explanation:
When dealing with a Poisson distribution, the mean (μ) is given by λ (lambda). In this case, since λ is equal to 16, the mean is also 16. The standard deviation for a Poisson distribution is the square root of the mean, so the standard deviation (σ) would be the square root of 16, which is 4.
Therefore, the standard deviation is 4.
