- USA Today (Feb. 17, 2011) described a survey of 1,008 American adults. One question on the survey asked people if they had ever sent a love letter using e-mail. Suppose that this survey used a random sample of adults and 205 stated that they had written a love letter using e-mail. Is this evidence that more than 20% of American adults have written a love letter using e-mail? Use a level of significance of 5%. a) p: (3 decimal places) b) Complete the following areas.
