OLUTION: Using the 68-95 X Desmos Scientific Calculato X (128) Lil Uzi Vert - Silly Wate ts/913042 mohammad Smart Assume that the readings at freezing on a batch of thermometers are normally distributed with a mean of O'C and a standard deviation of 1.00°C. A single thermometer is randomly selected and tested. Find Prethe 86-percentile. This is the temperature reading separating the bottom 86% from the top 149 Points possible: 3 This is attempt 1 of 3 E Submit

Answer 1

Solution:

According to question,

Z ~ N (0, 1)

With P-Value = 0.86

So, the corresponding Z-Score to left is : 1.08

Now, P86 = 1.08 oC (Answer)

This is the temperature reading seperating the bottom 86% from the top 14%.
