9. azombie comes up to you and shows you some data from a study it conducted. the zombie is interested in whether students' brains are tastier than those from the general population. based on the zombie's experience, it concluded that the population's mean brain tastiness is u= 80. to test the question, the zombie collects a sample of 15 students' brains and does a tasting test. afterwards, the zombie finds the sample mean is m=109 with ss 700 according to the zombie's data, are students' brains significantly tastier than those from the general population? report the appropriate statistics to justify your conclusion. if there is a significant difference how big is the difference? 10. you conduct a study to determine if interaction style has an effect on an individual's general depression. to test this, you recruit a group of men and women, measure their interaction style, and administer a scale that measures general depression. use the spss output below. overall (ignoring gender), did interaction style have a significant effect on depression? if so, how did it affect depression scores? ifthere is a significant difference, how big is the difference? how much variance in depression scores can be explained by interaction style? descriptive statistics dependent variable: depression mean std. deviation n gender interaction styte 10.46991 aggressive 7 male 14.4286 passive 75.1429 17.09219 7 74.4286 23.85971 moderate 54.6667 total 33.78511 21 18.7143 15.92393 female aggressive passive 77.7143 12.13417 moderate 73.1429 13.77714 total 56.5238 30.51822 21 total aggressive 16.5714 13.13664 14 76.4286 passive 14.30285 14 moderate 73.7857 18.72957 14 total 55.5952 31.81199 42 tests of between-subjects effects dependent variable: depression type il sum of squares mean squarer df sig source 32122.119* corrected modl 6424.424 24.683 000 129814.881 intercept 129814.881 498.755 000 gender 36.214 36.214 139 711 interaction_style 32028.905 16014.452 61.528 000 gender interaction_style 57.000 28.500 109 897 error 9370.000 36 260.278 total 171307.000 47 41492.119 corrected total 41
