a relief fund was set up in New York to collect donations for the families affected by recent storms. A random sample of 200 people who were contacted by telephone shows that 56 of them actually made contribution to the relief fund. A random sample of 200 who received first class mail requests showed that 36 of them actually made contributions to the relief fund.
Is there evidence at 5% level of significance that there is difference in the proportions of people who make donations if contracted by telephone or first class mail?

A random sample of 200 people who were contacted by telephone shows that 56 of them actually made contribution to the relief fund. A random sample of 200 who received first class mail requests showed that 36 of them actually made contributions to the relief fund.
