Recall our problem from chapter 4 (No. 7) where we were interested in the number of citizen complaints an individual officer received in 2013. We know that the sample mean "citizen complaint" is 8.4 and that n = 15 and the standard deviation is 6.75.
a. Calculate the standard error.
b. If an infinite number of sample means would be drawn, what percentage of police officers/citizen complaints will fall between ±1 standard deviation of the mean?
c. What range of citizen complaints would that be (with a standard error of 1.7)?
d. What is the range of citizen complaints/officer within 3 standard deviations from the mean (±)?
e. What is the technical term for these ranges?
