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). 1. a random sample of 11 nursing students from group 1 resulted in a mean score of 63.3 with a standard deviation of 3.7. a random sample of 13 nursing students from group 2 resulted in a mean score of 70.2 with a standard deviation of 6.6. can you conclude that the mean score for group 1 is significantly lower than the mean score for group 2? 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=0.05 for the test. assume that the population variances are equal and that the two populations are normally distributed. a: state the null and alternative hypotheses for the test.
b: compute the value of the t test statistic. round your answer to three decimal places
c: determine the decision rule for rejecting the null hypothesis h0. round your answer to three decimal places. reject or fail to reject your hypothesis?
