A new set of measurements are obtained with the values 0, 1,2,
3, 4, 5, 6, 7, 8, 9, 10, 11, 12 and these values are found 0, 1, 2,
3, 4, 5, 6, 5, 4, 3, 2, 1, 0 times, respectively. Find the the
average value of the measurements and the statistical uncertainty
based on the measurements.

The following measurements (in picocuries per liter) were
recorded by a set of ozone detectors installed in a laboratory
facility:
267.7,294.8,296.5,246.2,232.2,269.3
Using these measurements, construct a 80%
confidence interval for the mean level of ozone present in the
facility. Assume the population is approximately normal.
Step 1 of 4 :
Calculate the sample mean for the given sample data. Round your
answer to two decimal places.

Bill and Sarah both have single sample data--Bill has n=4
measurements in his data set, and Sarah has n=28 in hers. Both
mistakenly conduct single sample t-tests rather than z-tests. For
whom is this situation more problematic (ie: for whom will the
results be less accurate), and why? Describe in terms of the z and
t distributions
