Answer:
True cost of the microwave is in 99% confidence interval: 
Explanation:
Relevant data:
As we want to know the 99% confidence interval, the significance level is:
We need to estimate a confidence interval by a two tailed normal bell. Then we have:
The z-value for a probability of 0.005 in a normal standard distribution is 2.576
Confidence interval is given by;:

Well, if we analyze this with a little more care we will see that what happens is exactly the opposite.
The calculated profit per unit for base-case, worst-case is, and best-case for the management of Brinkley corporation is:
<h3>The Profit per unit for base-case:</h3>
45 - 1 1- 24 - 3 = $7
<h3>Profit per unit for worst case:</h3>
45 - 12 - 25 - 3 = $3 per unit
<h3>Profit per unit for best case:</h3>
