Question 1132880: Assume that the readings on the thermometers are normally distributed with a mean of 0 degrees and standard deviation of 1.00degreesC. A thermometer is randomly selected and tested. Draw a sketch and find the temperature reading corresponding to Upper P 93​, the 93 rd percentile. This is the temperature reading separating the bottom 93 % from the top 7 %.
The temperature for Upper P 93 is approximately ?

z(0.93)=+1.475
z=(x-mean)/sd
1.475=(x-0)/1
x=1.475 degrees C.
