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 18 nursing students from Group 1 resulted in a mean score of 48.6 with a standard deviation of 6.8. A random sample of 12 nursing students from Group 2 resulted in a mean score of 61.9 with a standard deviation of 4.4. Can you conclude that the mean score for Group 1 is significantly lower than the mean score for Group 2? Let μ1 represent the mean score for Group 1 and

μ2 represent the mean score for Group 2. Use a significance level of α=0.05 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.

Step 2 of 4: Compute the value of the t statistic..Rond 3 decimal places

Step 3 of 4: Determine the decision rule for rejecting the null hypothesis Ho. Round your answer to three decimal places

Step 4 of 4: State the test conclusion
