. A researcher is studying the effects of temperature on eating behavior. It is known that the population normally eats an average of 21 grams of food a day. A random sample of N=100 and selected and put into a controlled atmosphere where the temperature is maintained at 90 degrees. The daily food consumption for the sample averages 18.7 with SS=2475 . Using a two-tailed test at the .05 level, can the researcher conclude that temperature has an effect on eating behavior? Compute the estimated d and r-squared to measure the size of the treatment effect
