Answer:
Total Material Variance = $2,400 Unfavorable
Explanation:
Total Materials Variance = Standard Cost - Actual Cost
Here, standard cost = Standard Quantity Standard Rate
Standard quantity for actual output = 5,400
Standard Rate = $2.00 per pound
Standard Cost = 5,400 $2.00 = $10,800
Actual Cost = Actual Quantity Actual Rate
= 6,000 $2.20 = $13,200
Total Material Variance = $10,800 - $13,200 = - $2,400 Unfavorable
Since the value is negative the variance is unfavorable, as actual cost is more than standard cost.
Answer:
And we can find this probability using the complement rule and excel or a calculator and we got:
Explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem
Let X the random variable that represent the rating score of a population, and for this case we know the distribution for X is given by:
Where and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability using the complement rule and excel or a calculator and we got:
