Would it be unusual to find more than 22 who are satisfied with the job the major airlines were doing. The result
is or is not unusual, because P(x>22)equals= ? under the assumption that the proportion of adults that are satisfied with the airlines is 64%. Thus, in 100
random samples of size 25, this result is expected in about how many of the random samples.

4. Comparing two population proportions (independent samples)
4. Comparing two population proportions (independent samples) Most major survey research organizations do not include wireless telephone numbers when conducting random-digit-dial telephone surveys. If there are differences between persons with and without landline phones, using a random-digit-dial telephone survey may introduce bias into the survey results. Data on a broad range of health topics are collected through personal household interviews of a representative sample of the U.S. civilian noninstitutionalized population in the National Health Interview Survey (NHIS) respondents are also asked about...
