Eric randomly surveyed 150 adults from a certain city and asked which team in a contest they were rooting for, either north high school or south high school. of the surveyed adults, 96 said they were rooting for north high while the rest said they were rooting for south high. eric wants to determine if this is evidence that more than half the adults in this city will root for north high school. which of the following is the correct alternative hypothesis?
choose the correct answer below.
a. if more than half of all adults in this city root for north high, 3 out of every 1000 randomsamples of the same size from this population would produce the same result observed in thisstudy or a result more unusual.
b. if half of all adults in this city root for north high, 3 out of every 1000 random samples of thesame size from this population would produce the same result observed in this study or a resultmore unusual.
c. there's a 0.3% chance that the null hypothesis is true.
d. it states that 3 out of every 1000 random samples of the same size from this population wouldproduce the same result observed in this study or a result more unusual.

Study published in the journal of personality and individual differences found that adults with adhd displayed more creative achievement than those who didn't have the disorder. "for the same reason that adhd might create problems, like distraction, it can also allow an openness to new ideas," says holly white, assistant professor of cognitive psychology. "not being completely focused on a task lets the mind make associations that might not have happened otherwise." white and priti shah at the university of michigan gave 60 college students – half of them with adhd – a series of tests measuring creativity across 10 domains. the adhd group scored higher across the board. the adhd group showed more of a preference for brainstorming and generating ideas than the non-adhd group, which preferred refining and clarifying ideas. the adhd status of the participants was established by asking whether the individual had ever been clinically diagnosed with adhd/add. the tests of creativity were pencil-and-paper tasks administered in a laboratory setting. each of the ten scales was comprised of multiple questions, the scores on which were summed (e.g., writing creativity: "how many words can you make from the letters in the word 'psychology' invention creativity: "write down as many uses for a paper clip that you can think of.") this procedure does allow for a participant to be scored as showing no creativity under these conditions. a) state the research question in plain language (i wonder if is related to (1 point) b) state the null hypothesis (1 point) c) state the research hypothesis (1 point) d) is the research hypothesis directional or non-directional (1 point) e) name the predictor / independent variable f) give the operational definition of the predictor / independent variable g) evaluate the construct validity of the predictor / independent variable.
