Suppose that 55% of all adultAmerioans believe that a major overhaul of the nation's health care delivery system is essential. What is the probability that more than 59% of a random sample of 200 adultAmerioans would hold this belief? 3 Click the icon to View the standard normal table. The probability that more than 59% of the random sample hold this belief is E. (Round to four decimal places as needed.) An employee survey conducted by a company two years ago found that 51% of its employees were concerned about future health care benets. A random sample of Y5 of these employees were asked if they were now concerned about future health care benets. Answer the following, assuming that there has been no change in the level of concern about health care benets compared to the survey two years ago. a. What is the standard error of the sample proportion who are concerned? b. What is the probability that the sample proportion is less than 0.50? c. What is the upper limit of the sample proportion such that only 4% of the time the sample proportion would exceed this value? a Click the icon to view the standard normal table. a. The standard error of the sample proportion is D. (Round to five decimal places as needed.) b. The probability that the sample proportion is less than 0.50 is El. (Round to four decimal places as needed.) c. The upper limit of the sample proportion is D. (Round to two decimal places as needed.)
