The body weight of a healthy 3-month old colt should be about ?=60??μ=60kg . Suppose you want to test the claim that the weight of a wild Nevada colt (3-months old) is more than 60 kg.   State in words what a Type I Error is.

If someone's diastolic pressure is above average, would you expect that person's systolic pressure to be above or below average?

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. Q) If a participant has the same corneal thickness in their normal eye as the eye with Glaucoma, what would be the value for difference: measured as the corneal thickness of normal eye – corneal thickness of eye with Glaucoma.

State the conditions for applying the Chi-square test. What cautions are to be taken in using this test?

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. Is it possible…

Suppose that a customer is purchasing a car. He conducts an experiment in which he puts 10 gallons of gas in the car and drives it until it runs out of gas. He conducts this experiment 15 times on each car and records the number of miles driven. Median for Car 2 M = 250 mi / 10 gal (Type an integer or decimal rounded to one decimal place as needed.)
