Glaucoma is a leading cause of blindness in the United States, N. Ehlers measured the difference in corneal thickness (in microns) between the two eyes of eight patients. Each patient had one eye that had glaucoma and one eye that was normal. The difference was measured as the corneal thickness of normal eye – corneal thickness of eye with Glaucoma. Corneal thickness is important because it can mask an accurate reading of eye pressure. Use ? = .05. Hypothesis: H0: μd=0Ha: μd≠0 Using output Test statistics : t=0.134P value=0.897 Degrees of freedom (df): df=7 Level of significance: α=0.05 Decision: P value > 0.05 thus we fails to reject null hypothesis. Question a)Write a report summarizing your findings. When writing the report consider that medical staff estimate that a difference of 4.5 microns or more could impact on their ability to interpret eye pressure correctly. b) Define for the hypothesis stated in part b) what a type 1 error and type 2 error would mean.

A taxi business owner is determining the type of tires for his cars for efficiency the fuel can be increased. Twelve cars were tested using type A tires and asked to travel on a certain route. The same car and driver, then do the same route and the same road conditions with type B tires. Fuel consumption (km/liter) is then recorded as (enclosed). Note: • Use the last digit of your ID (2602296545) in place of a value; • If the last digit is 0 then it is changed to 1; Example: ID 1234567890 → 1 Can we conclude that a car with type A tires has material consumption fuel better than a car with type B tires? Assumed population normally distributed and α=5%. a. Define a hypothesis statement for the case. b. Perform statistical test calculations. c. Give a conclusion from the results of these calculations.
