1. Determine the p-value for H0: p=.5 versus HA: p =/ (difference) .5 when n=225 and p^ =.54.
2. A fast food company uses two management-training methods. Method 1 is a traditional method of
training and Method 2 is a new and innovative method. The company has just hired 36 new management trainees. 15 of the trainees are randomly selected and assigned to the first method and the remaining 16 trainees are assigned to the second training method. After three months of training, the management trainees took a standardized test. The test was designed to evaluate their performance and learning from training. The sample mean score and sample standard deviation of the two methods are given below. The management wants to determine if the company should implement the new training method.
mean standard deviation
method 1 69 3.4
method 2 72 3.8
Is there sufficient evidence to conclude that the new training method is more effective than the traditional training method? What is the decision at alpha=.05?
3. Assuming a normal population, use the data: 15, 19, 12, 14, 23 and 13 to test H0: meanv=18 versus HA: mean =/ difference) 18 at
alpha=.05
