1) an electronics firm determines that the number of defective transitors in each batch averages 15 with standard deviation 10. suppose that 100 batches are produced. use the chebychev inequality to estimate the number of batches having from 0 to 30 defective transitors.
2) If X is a random variable, then the variance of X equals the variance of X-a for any number a. Redo exercise 1 using this result wih a=70.
exercise 1 has a table that says : outcome: 70, 71, 72, 73; probability: .5, .2, .1, .2
