Pork producers and their neighbors are concerned about potential health safety and environmental issues associated with swine barns. The Veterinary Infectious Disease Organization (VIDO) conducted a 5-month air-quality study and found that there was no statistically significant increase in airborne pollutants 600 meters (m) downwind from a swine barn. Let X be the increase in airborne pollutants measured 600 m downwind from the swine barn. (Source: Swine barns are not a downwind health threat. Canadian Veterinary Journal
a. Determine the null and alternative hypotheses.
b. Sample data indicated that the null hypothesis should not be rejected. State the conclusion of the researcher in context of the problem.
c. Suppose, in fact, there is an increase in airborne pollutants 600 meters downwind from a swine barn. Was a Type I or Type Il error committed?

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
