Of the 98 participants in a drug trial who were given a new experimental treatment for arthritis, 56 showed improvement. Of the 92 participants who were given a placebo, 49 showed improvement. Construct a two way table for this data and then use a 0.05 significance level to test the claim that improvement is independent of weather the participant was given the drug or a placebo.

I'm stuck!!! Thanks!!
