A random sample of 50 measurements is obtained from a
A random sample of 50 measurements is obtained from a population. Let M be the median for the population. The research study requires an estimate of M. The sample median is deter-mined to be 37 .8. is determined to be 37.8. The researchers want to assess a range of values for this point estimator.
a. Display a 95% confidence interval on M by obtaining the values of La/2 and Ua/2.
b. Obtain a 95% confidence interval on M using the large-sample approximations of La/2 and La/2. Compare the two confidence intervals.
c. Provide reasons for the difference in the two confidence intervals.
