Answer:
Now we can calculate the degrees of freedom for the statistic given by:
And we can calculate the p value given by:
Since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis so then we can conclude that the outcomes are equally likely
Step-by-step explanation:
We need to conduct a chi square test in order to check the following hypothesis:
H0: There is no difference in the frequencies
H1: There is a difference in the frequencies
The level of significance assumed for this case is
The statistic to check the hypothesis is given by:
The observed values are:
Value 1 2 3 4 5 6
Frequency 26 32 44 37 27 34
And the expected values are for this case the same
And now we can calculate the statistic:
Now we can calculate the degrees of freedom for the statistic given by:
