Let Z be a standard normal random variable and calculate the following probabilities, indicating the regions under the standard normal curve?
a) $P(0 < Z < 2.17)$
b) $P(-2.50 < Z < 2.50)$
So I used the Normal Distribution Calculator to obtain:
$P(0 < Z < 2.17) = 0.98500 - 0.50000 = 0.485$
Similarly I got for b):
$P(-2.50 < Z < 2.50) = 0.99379 - 0.00621 = 0.98758$
I'm really not sure how to "indicate the region though"
I tried looking at this table Standard Normal Distribution Table
Yet I am not really sure how to use it..Looking at the table would that mean that the region my answer $0.485$ would be in is $8$%?
