A study was designed to compare the attitudes of two groups of nursing students towards computers. Group 1 had previously taken a statistical methods course that involved significant computer interaction. Group 2 had taken a statistic methods course that did not use computers. The students' attitudes were measured by administering the Computer Anxiety Rating Scale (CARS). A random sample of 15 nursing students from Group 1 resulted in a mean score of 41.5 with a standard deviation of 4.2. A...

A study was done on proctored and nonproctored tests. The results are shown in the table. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard n deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both parts. H2 35 81.88 20.96 34 x 74.84 10.56

A study was done to compare the amount of time per day students at public and private universities spend on Facebook. The study was composed of 200 students from a private university and 300 students from a public university. The time that students at a private university spent on Facebook had a Normal distribution with a mean of 220 minutes and a standard deviation of 36 minutes. The time that students at a public university spent on Facebook had a...
