Excel 2010 Preview #8: Five New T Distribution Functions that Replace TINV & TDIST

T.INV, T.INV.2T, T.DIST, T.DIST.RT, T.DIST.2T replace the old T functions: TINV, TDIST. The old T functions only did upper tails and were not similar to other Distribution functions. The new T functions allow us to do upper tail or lower tail and they do negative infinity to the t value as well as allow us the cumulative probability function and the density function that can determine height of T-distribution Curve.
