Question

Assume that thermometer readings are normally distributed with a mean of 0"C and a standard deviation of 1.00°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 1.00 and 1.75 Click to view page 1 of the table, Click to view page 2 of the table Draw a sketch. Choose the correct graph below. A. O B. C. z=1.00 z 1.75 z-1.00 z-1.75 z=1.00 z=1.75 The probability of getting a reading between 1.00°C and 1.75°C is D Round to four decimal places as needed.)

Explanation / Answer

P(1<z<1.75)=P(z<1.75)-P(z<1)

from normal distribution table we get 0.9599-0.8413=0.1186

correct answer from graphs is A
