A study suggests that about 80% of students have a job. Researchers are planning a second study with a new sample of students. They'll use the new data to construct confidence intervals to estimate the # of students working a job. The researchers plan on using a confidence level of 90% and want a margin of error of no more than + or - 1%. If we assume p(with ^ on top)= 0.80, what is the smallest sample size required to obtain the desired margin of error?
A medical study followed a sample of 14 heart patients who had received electronic pacemakers. The time (in months) to the first electrical malfunction was recorded as follows: 23, 14, 20, 16, 22, 14, 12, 8, 12, 24, 14, 10, 20, 16 Find the 95% confidence interval for the population mean. Please type only the upper interval with three decimal places. For example if CI= ( 10.25, 15), you type 15 as your answer.
