Probability Plot Problem:
Considering the following observations for X:
X = [19.0, 16.0, 14.0, 13.0, 12.0, 11.0, 10.5, 10, 9.7, 9.2, 8.7, 8.5]
a) Use Minitab to determine the type of probability distribution for X. Cut & paste the chart and briefly describe the reason for your answer.
b) Use the trendline in Excel to determine the equation f(x) for the observations. Cut & paste the chart with the trendline equation.
c) According to the above f(x), what is the predicted value of the next observation in the series?
