4 step problem:1. State the knoll and alternative hypothesis for the test.2. Compute the value of the t test statistic round the answer to the 3 decimal places.3. Determine the decision rule for rejecting the no hypothesis HO round your answer to the nearest 3 decimal places.4. State the test conclusion does it reject the null hypothesis or fail to reject the null hypothesis

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 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 * represent the mean score for Group 1 and z represent the mean score for Group 2. Use a significance level of a = 0.1 for the test. Assume that the population variances are equal and that the two populations are normally distributed. Step 1 of 4: State the null and alternative hypotheses for the test. Answer 1 Point #H Tables Keypad Keyboard Shortcuts Prev
