An article in the journal PLOS ONE describes a study in which the oviposition preferences of Tecia solanivora, the Central American potato tuberworm or Guatemalan potato moth, are compared across different varieties of Solanum
tuberosum (potato).
Suppose that Paul, a plant pathologist, collects a sample of 194 potato plants. Paul records the total number of T. solanivora
eggs laid on and around each plant. The egg counts are provided in the data file.
The data are available should you be required or wish to use software to answer the question.
