It is believed that a button can be pressed an average of 10000 times until it fails, where its lifetime varies according to a Geome distribution with probability p of failing in any press. From a sample of 32 buttons, it was found that the average lifetime was approximately 6000 presses. Using the maximum likelihood estimate, p, and the hypothesised value, po, compute the value of 2 E(p) – e(po)l- 7.09 (Provide your answer to two decimal places.)
