Explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What guaranteed mileage should the manufacturer announce
Only until the 5th percentile will have to be replaced, which is the value of X when Z has a pvalue of 0.05. So it is X when Z = -1.645.




The manufacturer should announce a guaranteed mileage of 44528 miles
Answer:
a. Suppose that if you receive the stock bonus, you are free to trade it. Which form of the bonus should you choose? What is its value?
I would choose the stock bonus because the current market price = 200 x $64 = $12,800 which is much higher than $4,600 (cash bonus)
b. Suppose that if you receive the stock bonus, you are required to hold it for at least one year. What can you say about the value of the stock bonus now? What will your decision depend on?
Even if you are required to hold the stock for one year, the price difference with the cash bonus is too great = ($12,800 - $4,600) / $4,600 = 178% higher. Since you are employed by the company, you should know if the company is doing well or not, and the probable future stock price.
Only if something catastrophic happened to the company would make the cash bonus more attractive.
