Answer the following, assuming that there has been no change in the level of concern about health care benefits compared to thesurvey bwo years agoa What is the standard enor of the sample proportion who are concerned?b. What is the probability that the sample proportion is less than 0.507cWhat is the upper limit of the sample proportion such that only 4% of the time the sample proportion would exceed this value?Click the icon to view the standard normal tablea The standard error of the sample proportion is(Round to five decimal places as needed.)CE

You may need to use the appropriate appendix table or technology to answer this question. A market research firm conducts telephone surveys with a 26% historical response rate. What is the probability that in a new sample of 600 telephone numbers, at least 150 individuals will cooperate and respond to the questions? In other words, what is the probability that the sample proportion will be at least 150 600 = 0.25? Step 1 Recall that a sampling distribution of p is a discrete probability distribution but can be approximated by a normal distribution when np ≥ 5 and n(1 − p) ≥ 5, where n is the sample size and p is the population proportion. Let p be the population proportion of people who respond to questions in telephone surveys. Here, it is given that 26% of people respond to questions in telephone surveys. Converting this percentage to a proportion gives p = . There is a sample of 600 telephone numbers, so n = .
