It is thought that the front cover and the nature of the first question on mail surveys influence the response rate. An article tested this theory by experimenting with different cover designs. One cover was plain; the other used a picture of a skydiver. The researchers speculated that the return rate would be lower for the plain cover. Cover Number Sent Number Returned Plain 205 101 Skydiver 211 108 Does this data support the researchers' hypothesis? Test the relevant hypotheses using α = 0.10 by first calculating a P-value. State the relevant hypotheses. (Use p1 for the plain cover and p2 for the skydiver cover.)
