Assume the readings on thermometers are normally distributed with a mean of 0degreesc and a standard deviation of 1.00degreesc. find the probability that a randomly selected thermometer reads between negative 0.99 and negative 0.32 and draw a sketch of the region.

 0.2134

Step-by-step explanation:

Given : Mean readings on thermometers =

Standard deviation =

We assume that the readings on thermometers are normally distributed.

Let x be the random variable that represents the reading on a random thermometer.

To find z-score :

For x = -0.99

For x= -0.32

By using the standard normal distribution table , the probability that a randomly selected thermometer reads between -0.99 and -0.32 will be :-
