Eighty cоllege students were аsked tо rаte twо scientists, one mаle and one female, on their knowledge about their topic areas. Each student was given two passages to read: one passage was about the numerous bio-domes in the world (“Biology”) and another passage was about enhancing the education of elementary school children (“Education”).Half of the students were told that the Biology passage was written by a female and the Education passage was written by a male. The other half of students were told the Biology passage was written by a male and the Education passage was written by a female. Then students rated the scientist’s knowledge on their topic areas on a scale ranging from 1 (“Does not display a professional level of knowledge”) to 100 (“Displays a thorough knowledge of the topic”).A two-factor ANOVA was conducted, and the mean ratings are listed below for each scientist gender and topic area condition. Assume that any effects (or mean differences) you measure are statistically significant. Scientist Gender Female Male Topic Area Biology 85 75 Education 65 75 a) State whether the results show main effects and/or an interaction. b) Significant or not, clearly describe each of these effects and the interaction in Plain English. I am expecting you to interpret the patterns not an omnibus interpretation.
Abby purchаsed 20 аcres оf undevelоped lаnd fоr $100,000; the land was zoned only for agricultural use. She hoped to have the city rezone the land into the RC Zone, where residential condominiums were permitted, together with agricultural uses. Three months later, at Abby’s request, the city rezoned Abby’s land into the RC Zone, which allowed up to 10 condominium units per acre. A few minutes later on the same day, the city council adopted an ordinance which provided that: “Anyone who builds condominium units in the RC Zone must reserve 10% of the units for sale to very-low-income buyers (those with an annual income of less than $10,000), and each unit sold to a very-low-income buyer may not be sold for more than $25,000.” Abby originally planned to sell 200 units for $250,000 each, producing $50,000,000 in sales proceeds. She anticipated that the total cost of the project (including construction cost and land cost) would be $40,000,000, giving her a profit of $10,000,000. If she must sell 20 of the units for $25,000 each, this will reduce her profit to $5,500,000. Abby sued the city on the theory that the ordinance was a taking. Which outcome is most likely?
