The ages​ (years) of three government officials when they died in office were 58​, 44​, and 60. a. Assuming that 2 of the ages are randomly selected with​ replacement, list the different possible samples.

(58,58), (58,44), (58,60), (44,58), (44,44), (44,60), (60,58), (60,44), (60,60)

b. Find the range of each of the​ samples, then summarize the sampling distribution of the ranges in the format of a table representing the probability distribution.
c. Compare the population range to the mean of the sample ranges.
d. Do the sample ranges target the value of the population​ range? In​ general, do sample ranges make good estimators of population​ ranges? Why or why​ not?

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
