When working on a normal distribution other than the standard normal distribution you need to either first convert to the z-scores and then find probabilities using the standard normal distribution (N(0,1)) OR when using technology you can input the mean and standard deviation. P (a < X < b) = normalcdf(a,b,μ, o)=normalcdf(staring data value, ending data value, mean, standard deviation) to find the probability given the interval of data values. This is equal to P(

Transcribed Image Text:When working on a normal distribution other than the standard normal
distribution you need to either first convert to the z-scores and then find
probabilities using the standard normal distribution (N(0,1)) OR when using
technology you can input the mean and standard deviation.
P (a < X < b) = normalcdf(a,b,μ, o)=normalcdf(staring data value, ending data
value, mean, standard deviation) to find the probability given the interval of data
values.
This is equal to P(<Z<b) = normalcdf(ª, b)-normalcdf(smaller z-score,
larger z-score)
For finding the data value given the area you can use invNorm. Again you either
need to convert the z-score back to the data value OR tell the calculator the mean
and standard deviation.
invNorm(area to the left, mean, standard deviation) = data value =X
invNorm(area to the left) = Z = Z-score. Then X = μ + Z. o
For the distribution N(9,3) match the probabilities below:
