in
a survey of consumers aged 12 and older , respondents were asked
how many cell phones were in use by the household.(No two
respondents were from the same household) Among the respondents ,
216 answered"none", 288 said "one", 376 said "two", 136 sid"
three", and 34 respondents with four or more . A survey respondent
is selected at random. Find the probability that his/her household
has four or more cell phones in use. Is it unlikely for a housild
to have four or more cell phones in use? Consider an event to be
unlikely if its probability is less than or equal to 0.05.

survey on obesity. Adults are considered obese if their body mass
index (BMI) is at least 30. The researchers wanted to determine if
the proportion of women in the south who are obese is less than the
proportion of southern men who are obese. The results are shown in
the table below.
