Make sure you can do the following problems as well:

1. The mean score on an exam was 80% with a standard deviation of 3. Use Chebyshev’s Theorem to find intervals such that:
   • at least 75% of the grades on the exam lie in that interval
   • at least 88.9% of the grades on the exam lie in that interval
   • at least 93.8% of the grades on the exam lie in that interval
2. Find the mean, median, Q1, Q3, IQR, range, variance and standard deviation of the following population data: 21, 13, 20, 19, 25, 23, 25, 34, 18, 30, 27, 12
3. For a random sample of tropical cyclones, the following data is calculated to study the relationship between the barometric pressure (x, in millibars) and the wind speed (y, in miles per hour): , , , , and r = -0.99.
   • Find the equation of the best-fit line.
   • What wind speed is predicted for a cyclone with a barometric pressure of 950 millibars?
   • If the cyclones in our random sample had barometric pressures ranging between 930 and 1000, is the prediction in the previous part reasonable? Is that prediction an interpolation or extrapolation?
