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 11 11 nursing students from Group 1 resulted in a mean score of 53.1 53.1 with a standard deviation of 4.4 4.4 . A random sample of 17 17 nursing students from Group 2 resulted in a mean score of 63 63 with a standard deviation of 3 3 . Can you conclude that the mean score for Group 1 is significantly lower than the mean score for Group 2? Let 1 1 represent the mean score for Group 1 and 2 2 represent the mean score for Group 2. Use a significance level of =0.01 = 0.01 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 2 of 4 : Compute the value of the t test statistic. Round your answer to three decimal places
