Question 1056710: Readings on a thermometer are normally distributed with a mean of 0C° and a standard deviation of 1.00.
What is the probability that a randomly selected thermometer reads:
a. Less than 0.53. (2 points)
b. Greater than -1.11 (2 points)
c. Between 1.00 and 2.25 (2 points)
d. Greater than 1.71 (2 points)
e. Less than -0.23 or greater than 0.23 (2 points)
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! z<0.53 has probability 0.7019
greater than -1.11 0.8665
between 1.00 and 2.25 0.1464
greater than 1.71 0.0436
less than -0.23 or greater than 0.23 is 1- the probability in between. The answer is 0.8181
Go to 2nd VARS and 2 for normal CDF
For the first, put in -6 or -9999, any negative number that is at least 6, then comma then 0.53. That will give the left tail.
For the second, put in -1.11,6, and that will give the right tail.
