The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 7.3% of his customers buy a magazine and he thinks that he might be able to use the display space to sell something more profitable. Before making a final decision, he decides that for one day he will keep track of the number of customers that buy a magazine. (a) Explain why this is a binomial experiment. (b) Assuming his suspicion that 7.3% of his customers buy a magazine is correct, what is the probability that exactly 6 out of the first 12 customers buy a magazine? Give your answer as a decimal number rounded to two digits. (c) What is the expected number of customers from this sample that will buy a magazine?

A researcher claims that exactly 40% of all adults in the U.S. use their cell phone for most of their online browsing. You believe that the true proportion is different. To test this, you take a simple random sample of 200 adults in the U.S and find that 44% of them use their phone for most of their online browsing. Test at 5% significance.

A newspaper conducted a statewide survey concerning a proposal to raise taxes in order to prevent budget cuts to education. The newspaper took a random sample (assume it is an SRS) of 400 registered voters and found that 160 would vote to raise taxes. Let p represent the proportion of registered voters in the state that would vote to raise taxes. (Round your answers to 4 decimal places, if needed.) (a) The standard error for the sample proportion is (b) The margin of error for an 88% confidence interval for p is Check
Polling 2004. In the 2004 U.S. presidential election,the official results showed that George W. Bush received50.7% of the vote and John Kerry received 48.3%. RalphNader, running as a third-party candidate, picked uponly 0.4%. After the election, there was much discussionabout exit polls, which had initially indicated a differentresult. Suppose you had taken a random sample of 1000voters in an exit poll and asked them for whom they hadvoted.a) Would you always get 507 votes for Bush and 483 forKerry? b) In 95% of such polls, your sample proportion of vot-ers for Bush should be between what two values? c) In 95% of such polls, your sample proportion of vot-ers for Nader should be between what two numbers? d) Would you expect the sample proportion of Nadervotes to vary more, less, or about the same as thesample proportion of Bush votes? Why?
