Do hypothesis test at the 1% level to decide if this result provides statistically significant evidence that you have improved your ability to throw a 6. Take a null hypothesis that there is no change in your ability.

****

My alternative hypothesis : That there is a change and p>0.2

and I know I have to use a 1-sided test.

I'm unable to define the test statistics (although my lecturer says its k=5 where k=# of 6 out of 20 trials).

I'm meant to use the Binomial tables to determine the RR, how do i do this.

Answers given is that: we dont reject null hypothesis, and the rejection region is k>=7.

That's it! =) Please do help, I have an exam tomorrow!
