A study was designed to compare the attitudes of two groups ofnursing students towards computers. Group 1 had previously taken astatistical methods course that involved significant computerinteraction. Group 2 had taken a statistic methods course that didnot use computers. The students' attitudes were measured byadministering the Computer Anxiety Rating Scale (CARS). A randomsample of 10 nursing students from Group 1 resulted in a mean scoreof 65.8 with a standard deviation of 5.1. A random sample of 16nursing students from Group 2 resulted in a mean score of 70.4 witha standard deviation of 7.6. Can you conclude that the mean scorefor Group 1 is significantly lower than the mean score for Group 2?Let ?1 represent the mean score for Group 1 and ?2 represent themean score for Group 2. Use a significance level of ?=0.05 for thetest. Assume that the population variances are equal and that thetwo populations are normally distributed.
Step 1 of 4: State the null and alternative hypotheses for thetest.
Step 2 of 4: Compute the value of the t test statistic. Roundyour answer to three decimal places.
Step 3 of 4: Determine the decision rule for rejecting the nullhypothesis H0. Round your answer to three decimal places.
Step 4 of 4: State the test's conclusion.
