Answer 1

The first page contains both the answers.

I have calculated them by using minitab in the Stat->Tables->Cross tabulation and chi square section

It can also be done in R with chisq.test function

The next two pages have the theory are chi square test if they are at all required by you.It was not getting uploaded so I had to reduce the quality a lot.In case of any doubts in the theory please comment as the photos are a bit unclear.
