You're trying to get an interval estimate (a Conf. Interval) for the average temperature of patients at your hospital. You can't run the populatin, as your software isn't equipped for that. So you must take a sample. You sample 49 patients, and the sample average temperature was 100.1 degrees F. Assume a population standard deviation of 1 degree. At 90% confidence, what is the margin or error? (Leave your answer in two decimal places, and don't incude a dollar sign. ex: 100.23)

Question

Definition Definition Method in statistics by which an observation’s uncertainty can be quantified. The main use of interval estimating is for describing a range that is made by transforming a point estimate by determining the range of values, or interval within which the population parameter is likely to fall. This range helps in measuring its precision.
