Lecture(12.8A) A researcher thinks that people have become more anxious when they hear about violent crime in the news. He asked a group of random participants to fill out two questioners. One questionere measured anxiety on a point scale from 1 to 10 with high anxiety resuting in higher scores. The other questionare asked participants to report the incidents of violent crime they had heard about (throuh media or face- to-face cummincation) in the last two weeks. The researcher gave the participants a score based on the total number of incidents reported. (1) What type of test should the researcher use to test this hypothesis.? (2) What would be the null and alternative hypotheses for this study? (Select two answers for each) (a) Z test (b)single sample t test (c)dependent sample t-test (d) independent sample t -test (e) ANOVA (f) Pearson correlation t-test (roe) (g) Chi Square goodness of fit test.
