Question
1 veterinarian wants to know if there is a difference in the glucose concentration in the anterior chamber of the left and right eyes of dogs. So he measured the concentration in both eyes in a random sample of 35 dogs and calculated a 95% confidence interval for the mean difference in glucose concentration between the two eyes: [-1.I mg/dLi, 0.7 mg/dL.i]. Which statistical test is appropriate for this analysis? (pt) a. Suppose you confirmed that the glucose measurements from the left eyes were normally distributed and the measurements from the right eye were also normally distributed. Is this sufficient to know if the assumptions of this analysis are met? Why/why not? ept) b. What does the confidence interval indicate about there being a significant difference in the mean glucose concentration between the two eyes? Explain how you know. (2pt) c.Explanation / Answer
a)
We can use two sample mean t test.
b)
Assumptions :
1) Samples have to be randomly drawn independent of each other.
2) The populations from which the samples have been drawn should be normal
c)
Zero lies in the confidence interval. So at 95% confidence interval, we can conclude that the means are not significantly different.
