the range of values within which a population parameter is estimated to lie
standard error of p hat
level of certainty in the interval estimate, so your conclusion is that you are 95% confident that the interval you calculated contains π.
confidence interval for population proportion π:
where p hat denotes the sample proportion, n is the same size, z * represents the critical value from the standard normal distribution for the confidence level desires.
The measure of how confident you are that the interval does in-fact contain the true parameter value
z* (multiplier used with SE)
Margin of Error
2 * square root of p hat (1 - p hat)/n (half of confidence interval)
the sample is a simple random sample from the population of interest. Check the data collection.
Upper .010 critical value
