Table 3.

Number of replications needed to obtain a significant difference test with probability 80% when the quotient of the mean of the GMO and the comparator equals Θ = 2 for data which have a negative binomial distribution with mean μ for the comparator, mean Θμ for the GM plant, and dispersion parameter ω.
