Question

Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. A thermometer is randomly selected and top 16%. tested. Draw a sketch and find the temperature reading corresponding to P84 the 84th percentile. This is the temperature reading separating the bottom 84% o the Click to view page 1 of the table. Click to view page 2 of the table Which graph represents P84? Choose the correct graph below. OA. OB. OC. The temperature for P84 is approximately (Round to two decimal places as needed.)

Explanation / Answer

P(Z < z) = 0.84       

or, z = 0.99   

The temperature for P84 is approximately 0.990
