A 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: [-1.1 mg/dLi, 0.7 mg/dLi].

a. Which statistical test is appropriate for this analysis? (0.5pts)

b. 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? (0.5pts)

c. 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. (1 pt)

If 30 lb of rice and 30 lb of potatoes cost ? $27.60? , and 20 lb of rice and 12 lb of potatoes cost ? $15.04? , how much will 10 lb of rice and 50 lb of potatoes? cost?

Noel is hoping to make a profit (in $) on the school play and has determined the function describing the profit to be f(t) = 8t – 2654, where t is the number of tickets sold. what does the number 8 tell you?

I've been working on this for a few days and i just don't understand, it's due in a few hours. you.the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i.e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case.part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
