Acircle has a radius of 5/6 units and is centered at (3.6, 7.8) write the equation of this circle

What is the range for 31,39,29,34,37,24,36,33,34,28

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed
