Assume the readings on thermometers are normally distributed with a mean of 0°C and a standard deviation of 1.00degrees°C.

Find the probability that a randomly selected thermometer reads between −2.24 and −1.54 and draw a sketch of the region.

The probability is __? (Round to 4 decimals)

Homework Answers

Answer #1

Solution: We are given:

We are required to find:

Using the z-score formula, we have:

Now using the standard normal table, we have:

Therefore, the probability that a randomly selected thermometer reads between -2.24 and -1.54 is 0.0493
