b) Random-digit-dialing telephone surveys used to exclude cell phone numbers. If the opinions of people who have only cell phones differed from those of people who have landline service, the poll results may not represent the entire adult population. The Pew Research Center interviewed separate random samples of cell-only and landline telephone users who were less than 30 years old and asked them to describe their political party affiliation. Are the data suitable for testing the hypothesis of independence between age group and political party affiliation?

A Pew Research survey asked 2,373 randomly sampled registered voters their political affiliation (Republican, Democrat, or Independent) and whether or not they identify as swing voters. $35 \%$ of respondents identified as Independent, $23 \%$ identified as swing voters, and $11 \%$ identified as both. $^{21}$ (a) Are being Independent and being a swing voter disjoint, i.e. mutually exclusive? (b) Draw a Venn diagram summarizing the variables and their associated probabilities. (c) What percent of voters are Independent but not swing voters? (d) What percent of voters are Independent or swing voters? (e) What percent of voters are neither Independent nor swing voters? (f) Is the event that someone is a swing voter independent of the event that someone is a political Independent?
Probability
Defining probability
a poll of 2039 randomly selected adults showed that 96% of them own cell phones. the technology display below results from a test of a claim that 92% of adults own cell phones. use the normal distribution as an approximation to the binomial distribution, and assume a 0.01 significance level to complete parts (a) through (e) a) is the test two-tailed, left-tailed, or right-tailed b) the test statistic is ( rounded two decimals) c) the p- value ( rounded three decimals) d) what is the null hypothesis
