Question

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 signicant 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 nursing students from group 1 resulted in a mean score of 65.6 with a standard deviation of 7.6. a random sample of 8 nursing students from group 2 resulted in a mean score of 70.9 with a standard deviation of 4.9. can you conclude that the mean score for group 1 is significantly lower than the mean score for group 2? let m1 represent the mean score for group 1 and m2 represent the mean score for group 2. use a significance level of a=0.01 for the test. assume that the population variances are equal and that the two populations are normally distributed.

Step 1: Choose the correct option for the alternative hypothesis for the test. Ha:m1____m2

Step 2: Compute the value of the test statistic 3 decimal places

Step 3: Compute the p value round to 3 decimal places

Step 4: State the tests conclusions

Reject or fail to reject the null
