Dogs vary in size more than cats do. Suppose the weight of dogs (D) in a certain city has a mean of 28 pounds with a standard deviation of 14 pounds and the weight of cats (C) has a mean of 9.5 pounds with a standard deviation of 2 pounds. Cat weights are roughly Normally distributed but dog weights are skewed to the right. Suppose you select a random sample of 10 dogs and 8 cats. What is the probability that the sample mean weight of the cats is greater than the sample mean weight of the dogs?
a. approximately 0
b. 0.80
c. 0.05
d. 0.95
e. 0.99 .

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle
