6. Assume that thermometer readings are normally distributed with a mean of OC and a standard deviation of 100 C . A thermometer is randomly selected and tested. a. Assume 1.37% of the thermometers are rejected b. Create a graph. because they have readings that are too high and another 1.37% are rejected because they have readings that are too low. Find the two readings that are cutoff values separating the rejected thermometers from the others. 7. The IQ scores of high school students are normally distributed. a. Find the area to the left of x = 120 given a mean b. Create a graph. value of 100 and standard deviation of 15
