Question

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)

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**

Assume the readings on thermometers are normally distributed
with a mean of 0° C and a standard deviation of 1.00° C. Find the
probability that a randomly selected thermometer reads between
−1.94 and −0.31 and draw a sketch of the region. (Round to four
decimal places as needed.)

Using the Standard Normal Distribution. Assume that the
readings on scientific thermometers are normally distributed with a
mean of 0 °C and a standard deviation of 1.00 °C. A thermometer is
randomly selected and tested. In each case, draw a sketch, and find
the probability of each reading in degrees Celsius
A) Less than 2.75
B) Between 1.50 and 2.50

Assume that the readings on the thermometers are normally
distributed with a mean of 0 degrees and standard deviation of
1.00degreesC. A thermometer is randomly selected and tested. Draw a
sketch and find the temperature reading corresponding to Upper P
85, the 85 th percentile. This is the temperature reading
separating the bottom 85 % from the top 15 %.
