    Stats question
    The Springfield Meteorological Center wanted to determine the accuracy of their weather forecasts. They searched their records for those 300 days when the forecaster had reported a 70% chance of rain. They compared these forecasts to records of whether it actually rained on those particular days. The forecast of 70% chance of rain can be considered very accurate if it rained on:
    95% - 100% of those days.
    85% - 94% of those days.
    75% - 84% of those days.
    65% - 74% of those days.
    55% - 64% of those days.
    WHICH ONE?
