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

α=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.
