A die is rolled 600 times. The face with six spots appears 112 times. Is the die biased towards that face, or is this just chance variation? The null hypothesis is
so the theoretical probability would be 1/6 so in 600 rolls you would expect tehoretically 100 with 6 spots. so is 112 showing bias... for me... no...
Do you means that - The chance that the face with six spots appears is equal to 1/6, and the face appeared 112 times in the sample just by chance.
that correct 1/6... called theoretical probability... and you have run an experiment where you would expect 100 6 spots... the relative frequency in you results is 112/600
thats what I'm saying... there is a 2% difference between actual and theoretical results...
so the variation can be put down to random variation.
How do you go about finding the P-value for this problem? I tried to find it, and got P=1.86, and got it wrong.
