Given below are two statements:
Statement (I): As per "Harrington thumb rules" (ISTA rules), Viability of seeds depends on storage conditions where a) For each 1% decrease in seed moisture content, the storage life of the seeds is doubled; b) For each $10^{\circ}\text{F}$ ($5.6^{\circ}\text{C}$) decrease in seed storage temperature, the storage life of seed is doubled.
Statement (II): The arithmetic sum of storage temperature in $^{\circ}\text{F}$ and the % relative humidity should not exceed 100, with no more than half the sum contributed by the temperature.
