Yes. since half of 50 is 25 it is correct to say that 18 is less than half
Circumference of the wheel = pi*d = 26pi ins = 13pi / 6 feet
there are 8280 feet in 1 mile
The number of revolutions in travelling 1 mile = 5280 * 6
----------- = 776 revs
13 pi
Standard deviation=4.
let the mean be 12 and the score be 0 (therefore 12 point difference.)
0-12/s=-3 (s being standard deviation)
-12/4 = -3
