A study of the reliability of diesel engines was conducted on 14 engines. The engines were run in a test laboratory. The time (in days) until the engine failed is given here. The study was terminated after 300 days. For those engines that did not fail during the study period, an asterisk is placed by the number 300. Thus, for these engines, the time to failure is some value greater than 300.
Failure time (days): 130, 67, 300*, 234, 90, 256, 87, 120, 201, 178, 300*, 106, 289, 74
a. Calculate the measures of center for the 14 engines.
b. What are the implications of computing the measures of center when some of the exact failure times are not known?
