Decreasing the sample size while holding the confidence level the same will do what to the width of your confidence interval?
a random sample of graduate students were asked, "would you come back to school to get a second degree if you were given the opportunity? " of the 150 people surveyed, 127 of them said that they would do so. find a 95% confidence interval for the proportion of graduate students who would come back to school (z_{a/2}za/2= 1.96). round your answer to three decimal places.
the 99% confidence interval for a population proportion is [0.645, 0.737]. find the standard error involved in this confidence interval. (z_{a/2}za/2= 2.58).
