Question

Assume that thermometer readings are normally distributed with a mean of

0degrees°C

and a standard deviation of

1.00degrees°C.

A thermometer is randomly selected and tested. For the case​ below, draw a​ sketch, and find the probability of the reading.​ (The given values are in Celsius​ degrees.)

Between

0.500.50

and 1.50

The probability of getting a reading between

0.500.50degrees°C

and

1.501.50degrees°C

is?

Answer 1

P(Reading between 0.50 and 1.50 degrees)

= P(0.50 < z < 1.50)

= 0.2417
