The heights of a random sample of 50 college students showed a mean of 167.4 centimeters and a standard deviation of 6.9 centimeters. (a) Construct a 98% confidence interval for the mean height of all college students. (b) What can we assert with 98% confidence about the possible size of our error if we estimate the mean height of all college students to be 167.4 centimeters?

Larry wants to inscribe an equilateral triangle in a circle using only a compass and straightedge. He will first construct a circle and locate its center. He will then perform the following steps.Step 1: Set the width of the compass to the diameter of the circle. Step 2: Plot a point on the circle. Place the compass on this point and draw two arcs to cut the circle. These two points of intersection between the arcs and the circle represent two of the vertices. Step 3: Draw a segment between the two vertices. Adjust the width of the compass to the length of the segment. Place the compass on one vertex and draw an arc to construct the third vertex.Step 4: Draw a line from one vertex to the next to form an equilateral triangle.What is the error in Larry's construction?A. He did not draw a pair of perpendicular bisectors to construct two diameters of the circle.B. He drew only two arcs.C. He set the width of the compass to the diameter of the circle.D. He did not ensure that the length of the sides of the triangle was the same as the diameter of the triangle.
