15. In Norway, the distribution of birth weights for full-term infants whose gestational is 40 weeks is approximately normal with mean u= 3500 grams and standard deviation o = 430 grams [19]. An investigator plans to conduct a study to deter- age

Can someone please help me to solve the following question showing all work

Explain what Cohen's d and r2 measure when calculated for a t test

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. 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.)

The average reading score on certain tests is given by y = 0.153x +255.33, where x is the number of years past 1970. In what year would the average reading = score be 258.849 if this model is accurate? The average reading score would be 258.849 in D 58 (Type a whole number.) CIJ #tv N N A ال / Next

How to Compute t and p for the difference between means?

The test statistic for Ho: p = 0.75 versus HA: p > 0.75 is z = -3.05. What is the p-value for this test? Round to four decimal places. p-value
