Answer:
0.2983
Step-by-step explanation:
Let X be the reading on thermometer. Given that X is N(0,1)
We are to find the probability that a randomly selected thermometer reads between negative 0.12 and 1.02
Reqd probability =
.
Since this x is already normal std variable x=z
i.e. reqd prob = ![P(0.12](https://tex.z-dn.net/?f=P%280.12%3Cz%3C1.02%29%20%3D0.3461%20-0.0478%5C%5C%3D0.2983)
Hence answer is 0.2983
