The paper “The Curious Promiscuity of Queen Honey Bees (Apis mellifera): Evolutionary and Behavioral Mechanisms” (Annals of Zoology [2001]: 255–265) describes a study of the mating behavior of queen honeybees. The following quote is from the paper:
Queens flew for an average of 24.2 ± 9.21 minutes on their mating flights, which is consistent with previous findings. On those flights, queens effectively mated with 4.6 ± 3.47 males (mean ± SD).
The intervals reported in the quote from the paper were based on data from the mating flights of n 5 30 queen honeybees. One of the two intervals reported was identified as a 95% confidence interval for a population mean. Which interval is this? Justify your choice.
