I[itLIEETII'iIl'IiI 4 A company manufactures a computer device that can be used in different temperature range. The researcher in this manufacturing took a sample of 9 computer device and collects the infon'naticn on the temperature (\"C } and lifetime [in hours} of these computer devices. The increased in temperature will shortens the lifetime of the device. The date is as follows. Computer Device Temperature.
