exercises 3.86 to 3.89 give information about the proportion of a sample that agrees with a certain statement. use statkey or other technology to estimate the standard error from a bootstrap distribution generated from the sample. then use the standard error to give a 95% confidence interval for the proportion of the population to agree with the statement. statkey tip: use "ci for single proportion" and then "edit data" to enter the sample information. 3.86 in a random sample of 100 people, 35 agree.
