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 
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
Checking your profits vs expense, and seeing which areas generate more profit. From there, you can choose between putting more money into the areas that are more profitable to you & decreasing the amount of money into areas that don't do as well, or continue another season to see if it is the same (as results can vary depending on the supply vs demand)
hope this helps
Answer:
Contribution margin = $16
Explanation:
Contribution is the difference between the selling price and the variable cost.
Contribution margin = (Sales - variable cost )
Variable cost = Variable manufacturing + Variable selling cost
Variable cost = 18 + (15%× 40) = 24
Contribution margin = 40 - 24 = $16
Contribution margin = $16
The difference is only in the strategy the company wants to use. For some market segments calculating the cost of goods sold by the permanent or periodic method may be more advantageous and allow a better monitoring of business efficiency and profitability. Companies often choose the method that best fits their organizational strategy. The periodic method, for example, as used by Kelty Industries, can be useful for greater input and output control, process optimization, consumer behavior assessment, and other advantages. But if Howe and Kelty wanted to change the calculation method, it would not affect anything, as the result would be the same regardless of the calculation, periodic or daily.
