Let x1, be independent and identically distributed random variables, each with expected value ? = e[xi] = 2 and variance \sigma ^2 = var(xi) = 4. find an upper bound for p(x1+x2+···+x144 > 144) using the following steps:
(a) let z=x1+ x2++x144, and use rules of expectation and variance to find e[z]and var[z].
(b) let a be the difference between 144 and e[z].
(c) apply chebychev's inequality to z using the number a.
(d) use the fact that z is symmetrically distributed about its mean to connect your answer to (c) to the original question. (hint: draw a symmetric density curve for z, and mark the values e[z], (e[z]+a) and (e[z]? a.)
label regions in the graph with their corresponding probabilities.)

Over the past year, three of the star salesmen at family resorts international's corporate office have been lured away to competitors. on top of that, karina, the general manager of the sales department, has noticed that most employees come in, do their jobs, and leave. family resorts offers a good salary, benefits, and tuition reimbursement, as well as a number of development and training programs. most employees seem contented enough, but karina would like to do something to increase the level of engagement among her staff. what do you think karina should do?
