Question

Assume the readings on thermometers are normally distributed with a mean of OC and a standard deviation of 1.00°C. Find the probability that a randomly selected thermometer reads greater than 0.24 and draw a sketch of the region. Click to view of the table. Click to view page 2 of the table ОА The probability is

Answer 1

solution

z=0.24

P(z >0.24 ) =1 - P(z <0.24 )

Using z table, ( see the z value 0.24    in standard normal (z) table corresponding value is )

= 1 -0.5948

=0.4052

probability=0.4052

graph is correct B
