Exam 6: Introduction to Hypothesis Testing: Inferences About a Single Mean

Using this random sample of data, test the following hypothesis at the .05 level of significance using SPSS. Interpret the output including identifying the specific statistical procedure that has been used and reporting the extent to which the test is statistically significant. Include appropriate evidence (e.g., values from the output). DATA 21.00 16.00 12.00 8.00 9.00 4.00 7.00 2.00 9.00 11.00 15.00 10.00 7.00 14.00 10.00 17.00 8.00 3.00 2.00 6.00 :\mu=10 :\mu10
