Quiz Chapter 3A researcher had collected data on the forces exerted on the wires in a prosthetic limb during acontrolled movement. Unfortunately, the electronics sensor was faulty, so some data points weremissing from the collected data:Time (s)Force (N)2.110.425.212.096.79.0568Discover the missing data point at time = 3.9 s by using:(a)Lagrange interpolating polynomial that passes through three points.(b)Newton's divided difference (interpolation).

Body mass index (BMI) is a measure of body composition, which can be used to assess if someone is underweight, healthy weight, overweight but not obese, or obese. It is calculated as a person’s weight (measured in Kilograms) divided by his/her height (measured in meters) squared. We recorded 5 students’ BMI values and the numbers of hours they exercised in the past week, as following: BMI 18.4 19.6 20.5 27.6 30.6 Hours of exercise 3.0 2.5 4.0 2.7 0.5 What is the value of r?

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.

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.
