Question

Five fourth‐grade children were selected at random from the entire class and
timed in a short race. The times in seconds were :
6.3 4.2 4.7 6 5.7
Test the hypothesis that the distribution of times is uniform on the interval
from 4 to 8 seconds. Note that such a distribuƟon is given by :
 F*(x) = 0                                x < 4

         =(x - 4)/4                      4 equal to or less x < 8

          =1 for for X                   8 equal to or less x


Use α = 0.10
