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 signicant 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 17 nursing students from Group'i resulted in a mean score of 46.9 with a standard deviation of 5.3. A random sample of 9 nursing students from Group 2 resulted in a mean score of 56.3 with a standard deviation of 8.9. Can you conclude that the mean score for Group 1 is signicantly lower than the mean score for Group 2? Let m represent the mean score for Group 1 and p; represent the mean score for Group 2. Use a signicance level of a = 0.1 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 1 of 4: State the null and alternative hypotheses for the test
