Transcribed Image Text:Recall the following definitions from section 6.4 of the text.
The area under the normal curve from x = a to x = b with given mean and standard deviation is the probability that x assumes a value between x = a and x = b. If we are using Table IV in Appendix C, we need to
standardize the random variable x using the formula z = (x - P)/o, before using the table.
Alternatively, you may use a graphing calculator to obtain more accurate calculations without standardizing the random variable x.
For example, using a TI83 plus we calculate the area under the normal curve from x = a to x = b by using the
normalcdf(a,b,H,0)
where u is the mean and o is the standard deviation of the normal distribution. We use 1E99 for o and -1E99 for -o, if needed.
