Asked by Jen
The respiratory rate per minute in newborns varies according to a distribution that is approximately Normal with mean 50 and standard deviation 5.
The proportion of observations from a standard Normal distribution that take values less than 1.15 is about
(a)
0.1251.
(b)
0.8531.
(c)
0.8749.
The answer is C, but I'm unsure how to do this on a TI-89 using the normalCDF function
