Flies in the kitchen are annoying- not to mention the yuck factor if they land on your food. To test if the fly sprays available in Aotearoa New Zealand do the job that they claim to do, a selection of 10 fly sprays sold in NZ were tested to see: 1. How fast the sprays were at hocking down flies and 2. Whether the flies were dead after 24 hours. Researchers conducted their tests in an independent laboratory not in any of the manufacturer's laboratories. For each product: 4 half-second sprays were released into a specially built chamber measuring 5.8 m² and containing 20 house flies.

To test if the fly sprays available in Aotearoa New Zealand do the job that they claim to do, a selection of 10 fly sprays sold in NZ were tested to see: 1.

Researchers conducted their tests in an independent laboratory not in any of the manufacturer's laboratories. For each product: 4 half-second sprays were released into a specially built chamber measuring 5.8 m' and containing 20 house flies. They timed how long it took for 50% and 90% of the flies to be "knocked down". Twenty-four hours later, they recorded the number of flies that had died. Each test was repeated 5 times for each product. The test also included a control, where the flies weren't sprayed with anything. On average, 1 fly died in each control test. Consider the Sampling process a) What is the population of interest? b) What is the sample size? c) Name 2 variables tested in the sampling process? Page 3 of 11 &
