Dr. Caldwell was also interested in learning whether the anxiety of child victims is related to whether they testify in court. She conducted another research study in which she compared the anxiety levels of 10 children who testified to the anxiety levels of 10 children who did NOT testify. She measured the children’s anxiety using the same test described earlier - the Beck Anxiety Inventory for Children (BAI-C). The scores of the 20 children are as follows: TestifiedDid NOT Testify 5554 5762 5072 6269 6673 4858 7175 6063 7070 5266 11. Conduct an independent measures t-test to determine whether Dr. Caldwell can conclude that there is a significant difference between child victims who testify and those who don’t with respect to anxiety.

"Snoqualmie" is a name shared by a waterfall and a tribe of Native Americans. In a study of the cultural importance of the waterfall, two groups of the Snoqualmie tribe were randomly surveyed. One group consisted of Snoqualmie members living less than 25 miles from the waterfall. Another group consisted of Snoqualmie members living more than 25 miles from the waterfall. The researchers asked each member to rate the cultural importance of the waterfall as low, medium, or high. Data from the study are presented in the following table. Members Living More Than 25 Miles from the Waterfall Members Living Less Than 25 Miles from the Waterfall Total Low 25 17 42 Medium 8 21 29 High 12 17 Total 38 50 88 If the distributions of ratings are the same for those Snoqualmie members living less than 25 miles from the waterfall and those living more than 25 miles from the waterfall, which of the following is equal to the expected count of members living less than 25 miles from the waterfall who rated…

The Computer Anxiety Rating Scale (CARS) measures an individual’s level of computer anxiety, on a scale from 20 (no anxiety) to 100 (highest level of anxiety). Researchers at a large university administered CARS to 80 business students. One of the objectives of the study was to determine whether there is a difference between the level of computer anxiety experienced by female students and male students. Of the 80 student survey takers, 40 were male, 40 were female. The results are in the table below for statistical analysis of variability between the two samples. All of these analyses are run with a 95% level of confidence. Males Females Sample Mean 40.26 36.85 Sample Standard Deviation 13.35 9.42 Perform the test chosen in part (d) of the previous problem and supply this information: a. What is the value of the test statistic? b. Find the probability of getting these results if there is no difference in anxiety ratings between the…
