Question

Assume that the readings on the thermometers are normally distributed with a mean of 0 degree and standard deviation of 1.00 degree C. Assume 2.1% of the thermometers are rejected because they have readings that are too high and another 2.1 % are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others. Click to view page 1 of the table. Click to view page 2 of the table. Which graph represents the region in which thermometers are rejected? Choose the correct graph below.

Explanation / Answer

Since the lowest 2.1% and the upper 2.1% are rejected. the rejection reason is given by A which is top and bottom one on the normal bell curve
