mode excel {Ans: =MODE.SNGL(number 1, [number 2], ...)}rules of thumb to normal distribution probability {Ans: About 68% of the probability is contained in the range reaching one standard deviation away from the mean on either side, that is, P(μ-σ μ+σ) . About 95% of the probability is contained in the range reaching two standard deviations (1.96 to be exact) away from the mean on either side, that is, P(μ-2σ μ+2σ) About 99.7% of the probability is contained in the range reaching three standard deviations away from the mean on either side, that is, P(μ-3σ μ+3σ) . A z-value of a point x is the distance x lies from the mean, measured in standard deviations, z= .}mean excel {Ans: =AVERAGE(number 1, [number 2], ...)}Hypothesis Test Excel {Ans: =T.TEST(array1, array2, tails, type) Returns the p-value associated with a given t-test. array1 is a set of numerical values or cell references. array2 is a set of numerical values or cell references. If we only have one set of data, for the second data set we create a column for which every entry is the historical mean. tails is the number of tails for the distribution. It should be set
