In a survey, 44% of the respondents stated that they talk to their pets on the telephone. A veterinarian believed this result to be too high, so she randomly selected 240 pet owners and discovered that 98 of them spoke to their pet on the telephone. Does the veterinarian have a right to be skeptical? Use the a= 0.01 level of significance. 5% of the population size, and the sample V the requirements for testing the hypothesis satisfied. Because npo...

Question 6.3.14 In an article titled "Unilateral Nostril Breathing Influences Lateralized Cognitive Performance" that appeared in Brain and Cognition (1989), researchers Block et al. published results from an experiment involving assessments of spatial and verbal cognition when breathing through only the right versus left nostril. The subjects were 30 male and 30 female right handed introductory psychology students who volunteered to participate in exchange for course credit. Initial testing on spatial and verbal tests revealed the following summary statisticS Note...

1. A newspaper published an article about a study in which researchers subjected laboratory gloves to stress. Among 213 vinyl gloves, 63% leaked viruses. Among 213 latex gloves, 9% leaked viruses. Using the accompanying display of the technology results, and using a 0.10 significance level, test the claim that vinyl gloves have a greater virus leak rate than latex gloves. Let vinyl gloves be population 1. technology results: Pooled proportion: 0.36 Test statistic, z: 11.6982 Critical z: 1.2816 P-value:...
