1. New Army recruits are required to take a test called the Armed Services Vocational Aptitude Battery (ASVAB). The test measures vocational aptitude and is normally distributed with a mean (u) of 55. A recruiter wonders if soldiers who are nurses have higher than average ASVAB scores. To test this, the recruiter records the ASVAB scores of 37 nurses and finds their mean (M) score was 58.0 with a standard deviation (s) of 8.12. Do nurses have higher ASVAB scores than the average recruit? Use alpha= .05. I have analyzed the data using Jamoyi, and you can view those results on the next page. You will need those results to answer some of the questions below. a. (1 point) Is this a one or two-tailed hypothesis test? b. (1 point) If one tailed, which direction? c. (1 point) How many degrees of freedom are there for this test? d. (1 point) What is the alternative hypothesis? (In words and statistical notation) e. (1 point) What is the null hypothesis? (In words and statistical notation) 1 f. (1 point) We will make the decision to reject the null hypothesis when g. (3 points) Describe the characteristics of the sampling distribution. i. I ii. iii. < h. (2 points) What is the t value for this test? i. (2 points) What conclusion would you draw? Make sure to state your decision and tie the answer back to the problem. j. (1 point) What type of error might you have made? k. (2 points) What is the value for the effect size and what is the size of the effect. d= size== 1. (2 points) Calculate r2 and describe the size of the effect. 22² = size= 1. New Army recruits are required to take a test called the Armed Services Vocational Aptitude Battery (ASVAB).
