A researcher wants to know the effect of lighting on snacking behavior. He knows that young adults normally eat an average of =
21 grams of light snack food each day. He selects a random sample of n = 100 adults and places them in a controlled room where lighting is manipulated to mimic mid-day sunlight. Bowls of crackers are made available. Snack consumption for the sample averages M = 18.7 and s = 9.1. Does lighting impact snacking behavior?
The mean of the study was 18.7 grams, which is only 2.3 grams below the actual average grams of snacks that an adult would consume while at work, after revising this you could say that theres a significant reduction, but then the standard deviation is 9.1 this means that there are still adults that are eating more than 21 gram of snacks, so the test would result inconclusive.
