Astudy 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 9 nursing students from group 1 resulted in a mean score of 46.1 with a standard deviation of 5.9. a random sample of 14 nursing students from group 2 resulted in a mean score of 56.3 with a standard deviation of 7.9. 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=0.1for 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.
