Transcribed Image Text:Assume that the readings at freezing on a bundle of thermometers are normally distributed with a mean of
0°C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find the
probability of obtaining a reading greater than 2.042°C.
P(Z > 2.042) =
Expert Solution

Step 1
Let Z from the standard normal distribution with mean = 0 °C and standard deviation = 1 °C
Then,
We will find the probability P(Z > 2.042) = ?
