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 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 99 nursing students from Group 1 resulted in a mean score of 65 with a standard deviation of 6.2 A random sample of 77 nursing students from Group 2 resulted in a mean score of 74.2 with a standard deviation of 8.9 Can you conclude that the mean score for Group 1 is significantly lower than the mean score for Group 2? Let μ1μ1 represent the mean score for Group 1 and μ2μ2 represent the mean score for Group 2. Use a significance level of α=0.01 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.

Step 2 of 4:

Compute the value of the t test statistic. Round your answer to three decimal places.

Step 3 of 4:

Determine the decision rule for rejecting the null hypothesis H0H0. Round your answer to three decimal places.

Step 4 of 4:

State the test's conclusion.

Answer #1

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 1313 nursing students from Group 1 resulted in a mean
score of 68.668.6 with a standard deviation of 4.24.2. A...
