Answer:

The manufacturer should announce a guaranteed mileage of 44528 miles

Explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

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:

\mu = 47900, \sigma = 2050

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.

Z = \frac{X - \mu}{\sigma}

-1.645 = \frac{X - 47900}{2050}

X - 47900 = -1.645*2050

X = 44528

The manufacturer should announce a guaranteed mileage of 44528 miles

Vlada [557]

Answer:

$889.70

Explanation:

The computation of the net present value is shown below:

= Present value of all yearly cash inflows after applying discount factor - initial investment  

where,  

The Initial investment is $10,000

All yearly cash flows would be

= Annual amount received × PVIFA for 4 years at 4%  

= $3,000 × 3.6299

= $10,889.70

Refer to the PVIFA table

So, the net present value is

= $10,889.70 - $10,000

= $889.70
