specified to be normally distributed with a mean of 10,000 ohms and a standard deviation of 500 ohms, at a temperature of 25°C. Thus, only about 2.3% of these thermistors should produce resistances in excess of 11,000 ohms. The exact measurement of resistances produced is time-consuming, but it is easy to determine whether the resistance is larger than a specified value (say, 11,000). For 100 ther- mistors tested, 5 showed resistances in excess of 11,000 ohms. Do you think the thermistors from which this sample was selected fail to meet the specifications? Why or why not?

Question

Transcribed Image Text:10.34 The resistances of a certain type of thermistor are
specified to be normally distributed with a mean of
10,000 ohms and a standard deviation of 500 ohms,
at a temperature of 25°C. Thus, only about 2.3% of
these thermistors should produce resistances in
excess of 11,000 ohms. The exact measurement of
resistances produced is time-consuming, but it is
easy to determine whether the resistance is larger
than a specified value (say, 11,000). For 100 ther-
mistors tested, 5 showed resistances in excess of
11,000 ohms. Do you think the thermistors from
which this sample was selected fail to meet the
specifications? Why or why not?
