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
15
15 nursing students from Group 1 resulted in a mean score of
42.9
42.9 with a standard deviation of
2.8
2.8. A random sample of
12
12 nursing students from Group 2 resulted in a mean score of
48.4
48.4 with a standard deviation of
5.1
5.1. Can you conclude that the mean score for Group 1 is significantly lower than the mean score for Group 2? Let
μ
1
μ1 represent the mean score for Group 1 and
μ
2
μ2 represent the mean score for Group 2. Use a significance level of
α=0.01
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.
