A poll reported that 63% of adults were satisfied with the job the major airlines were doing. Suppose 20 adults are selected at random and the number who are satisfied is recorded. Would it be unusual to find more than 17 who are satisfied with the job the major airlines were doing? The result is/is not unusual, because P(x>17) = _____ under the assumption that the proportion of adults that are satisfied with the airlines is 63%. Thus, in 100 random samples of size 20, this result is expected in about ______ of the random samples. (Type integers or decimals. Round to four decimal places as needed.)
