Question
Assume that thermometer readings are normally distributed with a mean of 0 degree C and a standard deviation of 1.00 degree 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 =1.12 and 1.98 Click to view page 1 of the table. Click to view page 2 of the table. Draw a sketch. Choose the correct graph below. The probability of getting a reading between -1, 12 degree C and 1.98 degree C is (Round to four decimal places as needed.)Explanation / Answer
the probability is area under the graph between z = -1.12 and z= 1.98
correct choice is C)
P(-1.12 < Z < 1.98) = P(Z < 1.98) - P(Z < -1.12)
= 0.9761 - 0.1314
= 0.8447
