1. A researcher is interested in the average distance patients
traveled to the nearest health center. He collected a simple
random sample of 25 patients sampled from a population with an
unknown standard deviation. After collecting the data, he found
that sample mean is 15 miles, with a standard deviation of 3 miles
in the sample. The researcher wants to be 95% confident about his
estimate of the mean distance to the nearest health center in his
target population.
A) Calculate the standard error of the mean
B) Find out the margin of error (95% confidence) based on the
above information (Use the T distribution).
C) Construct a 95% confidence interval of the mean distance to
the nearest health center.
