Find the critical value of x2 based on the given information H1 >3.5 n=14 a=0.05

The degrees of freedom are given by:

The significance level is and then the critical value can be founded in th chi square table we need a quantile that accumulates 0.05 of the area in the right tail of the distribution and for this case is:

And if the chi square statistic is higher than the critical value we can reject the null hypothesis in favor of the alternative.

Step-by-step explanation:

We have the followign system of hypothesis:

Null hypothesis:

Alternative hypothesis:
