Study was designed to compare the Attitudes of two groups of nursing students toward computers. Group one had previously taken a statistical method course that involved significant computer interaction. Group 2 had taken to statistic methods course that did not use computers. The students attitude were measured by administrating the computer and anxiety rating scale (cars). A random sample of 13 nursing students from group one resulted in the mean score of 70 with a standard deviation of 2.6. A random sample of 8 nursing students from group 2 resulted in a mean score of 74.8 with the standard deviation of 4. Can you conclude that the mean score for group 1 is significantly lower than the mean score for a group 2? Let you u1 represent the mean score for group 1 and u2 represent the mean score for group 2. Use a significant level of a = 0.05 for the test. Assume that the population variance are equal and that the two populations are normally distributing. 1.State and null and alternative hypothesis for the test. 2.compute the value of the t test statistic. Round to three decimal places. 3.determine the decision rule for rejecting the null hypothesis Ho. Round to three decimals. 4.state the test conclusion.
