The following table gives the observed and expected frequencies in tossing a dice 120 times. For testing the hypothesis that the dice is fair , one is required to compute
Find the value.
The following table gives the observed and expected frequencies in tossing a dice 120 times. For testing the hypothesis that the dice is fair , one is required to compute
Find the value.
First compute the expected frequencies under the hypothesis
There are 120 throws and 6 equally likely outcomes, hence the expected frequency of each outcome is 120/6=20.
This is the expected number of 1, 2, .. 6's in 120 throws.
