11) An HDTV is made from 100 components. Each component has a .005 probability of being defective. What is the probability that an HDTV will not work perfectly?

12) Suppose that 48% of individuals 85 years and older have Alzheimers Disease. You go to a nursing home that has been feeding residents a diet consisting of natural, organic, and healthy foods including free range chickens, omega 3 eggs, flax seed, etc. You find that only 29 of 100 residents who are 85-years and older have Alzheimers disease? What is the likelihood of this outcome?

(Hint: solve this problem with Excel Using BINOMDIST. To use Excel, you need the following:

Number_S is the number of successes in n trials. For this problem = 29

Trials is the number of independent trials. For this problem = 100.

Probability_S is the probability of success on each trial. For this problem = .48

Cumulative is a logical value and you indicate TRUE if you want the cumulative value or FALSE for the exact probability. For this problem, we want the individual probability of 29 successes from 100 so we indicate FALSE.
