Question 1064556:
Assume that thermometer readings are normally distributed with a mean of 0degrees C and a standard deviation of 1.00 degrees 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 negative 1.25 and 1.61

You can put this solution on YOUR website! Assume that thermometer readings are normally distributed with a mean of 0 degrees C and a standard deviation of 1.00 degrees 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.)
-----
The sketch is a normal curve with mean = 0 and standar dev. = 1
---------------------
Between negative 1.25 and 1.61
P(1.25 < x < 1.61) = P(1.25< z < 1.61) = normalcdf(1.25,1.61) = 0.0520
