(a) Plot the data on lightning deaths.
(b) Describe the trend (if any) and discuss possible causes.
(c) Fit an exponential trend to the data. Interpret the fitted equation.
(d) Make a fore- cast for 2015, using a trend model of your choice (or a judgment forecast). Explain the basis for your forecast. Note: Time is in 5-year increments, so use t = 16 for your 2015 forecast.
