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 61.5 with a standard deviation of 4.6. A random sample of 7 nursing students from Group 2 resulted in a mean score of 68.4 with a standard deviation of 3.5. Can you conclude that the mean score for Group 1 is significantly lower than the mean score for Group 2? Let µj represent the mean score for Group 1 and u2 represent the mean score for Group 2. Use a significance level of a = 0.05 for the test. Assume that the population variances are equal and that the two populations are normally distributed.

![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
