We enter these values into the TI-84 using 2nd:DISTR:2:normalcdf(-10^99,365,300,50) and compute the cumulative probability. The answer is: P(X < 365) = 0.9032. Hence, there is a 90% chance that a light bulb will burn out within 365 days.

In the TI-84 PLUS calculator, the normalcdf command is used to find areas under a normal curve. Four numbers must be used as the input. The first entry is the lower bound of the area. The second entry is the upper bound of the area. The last two entries are the mean and standard deviation.

If P(-∞ < X ≤ x) = y, use invNorm (y, μ, σ) = x . Again, either σ, or μ and σ, can be omitted, in which case μ = 0 and σ = 1 are assumed. Examples. invNorm (0.5) = 0 because P(-∞ < X ≤ 0) = 0.5, invNorm (0.975) = 1.96 ≈ 2 because P(-∞ < X < 2) ≈ 0.975. t-distribution with n Degrees of Freedom: T(n)

#3: invNorm( inv = Inverse Normal Probability Distribution Function This function returns the x-value given the probability region to the left of the x-value. (0 < area < 1 must be true.) The inverse normal probability distribution function will find the precise value at a given percent based upon the mean and standard deviation.

Activity overview: - Texas Instruments
(TI-84 Plus family) — 11610 This activity utilizes MathPrintTM functionality and includes screen captures taken from the TI-84 Plus C Silver Edition. It is also appropriate for use with the TI-83 Plus, TI-84 Plus, and TI-84 Plus Silver Edition but slight variances may be found within the directions.
