Consider the given data set. n = 7 measurements: 5, 8, 2, 1, 9, 9, 5 Calculate the median. Calculate the upper quartile. Calculate the lower quartile.

After students were not doing so well in her math class, Mrs. Stevens decided to try a different approach and use verbal positive reinforcement at least once every hour. Use the following results to find a 95%95% confidence interval for the true mean change in the students’ test scores after Mrs. Stevens started using positive reinforcement. Assume that the population distribution of the paired differences is approximately normally distributed. Round to one decimal place.  Students' Test Scores Student Without Reinforcement With Reinforcement 1 6464 8080 2 7373 7474 3 6060 6767 4 6262 8181 5 4848 5050 6 7474 8888

For the following sample data, find M: 8 , 2, 2, 5, 3.
