(1) A researcher is wondering about the effects of different chemical stresses on the wing size of Drosophila (fruit flies). Stress often reduces overall wing size which he measures in four flies from each of three different species (Drosophila melanogaster, D. simulans, D. ananassae) exposed to three different treatments (paraquat stress, lead stress, mercury stress). df SS MS F p Source His data: mePqut LArcurySiros foy 52 203 45 Paraquat Lead 21 12 15 24 Mercury 12 19 25 D.mel...

4. Question 5.7. Johnson and Leone (Statistics and Experimental Design in Engineering and the Physical Sciences, Wiley, 1977) describe an experiment to investigate warping of copper plates. The two factors studied were the temperature and the copper content of the plates. The response variable was a measure of the amount of warping. The data were as follows: Copper Content (%) Temperature (C)40 100 17, 20 16,2 24. 22 28, 27 12.9 18, 13...

1. The operating characteristics of zinc-bromine batteries are partially dependent on the vapour pressure of the bromide compound, which is itself dependent on the temperature at which the battery operates. (a) In the data file RegressionTutorial.xlsx there are data of measurements of vapour pressure and the corresponding operating temperatures. Copy the data into Minitab and run a regression analysis. 1 mark for output (b) First perform an hypothesis test to see if there is a significant connection between the response...

Please explain answers A researcher is interested in the weight change of Canadian snow geese. She collects a random sample of snow geese and feeds some of them a diet of plants (labeled Plants) and some of them dog food (labeled Chow). The dataset is in the file snowgeese.xls. Of interest is whether the true average weight changes are different at the 1% significance level. Analyze the data. Report summary statistics. Justify and interpret the results. Be sure to state...
