Figure 2. Distribution of calving intervals observed after 8 years (2006–2013) of data collection in Port Ross, Auckland Islands, New Zealand. Total sample size (n = 45).
Figure 3. Density distributions of the 1000 resampled mean calving intervals for the range of sample sizes tested (n = 10, 100, 500, 1000, 2000).
Figure 4. Power analysis showing the change in alpha on the y-axis as the difference of the mean estimate increases on the x-axis with sample size of 45 calving intervals.
