Answer:
The answer is below.
Explanation:
The z score is a used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

a) Given that n = 100, μ = 2000, σ = 18
For x < 1995 millimeters:

From the normal distribution table, P(x < 1995) = P(z < -2.78) = 0.0027
b) P(z > z*) = 10% = 0.1
P(z < z*) = 1 - 0.1 = 0.9
z* = 1.28

From the normal distribution table, P(z < z
Answer:
$144 unfavorable
Explanation:
The computation of the overall fixed manufacturing overhead volume variance for the month is shown below:
But before that following calculations need to be done
Budgeted manufacturing overhead is
= 6600 × $1.20
= $7,920
And,
Manufacturing overhead applied is
= Standard hours × Predetermined overhead rate
= 6480 × $1.20 = $7,776
So, fixed manufacturing overhead volume variance is
= Fixed overhead applied - budgeted fixed overhead
= $7,776 - $7,920
= $144 unfavorable
Answer:
The correct answer is B. demand for good X will increase.
Explanation:
Two goods, X and Y, are said to be substitutes if they can be used to serve the same purpose. Thus, if good X is a substitute to good Y, then X can be used in place of Y and Y can be used in place of X.
For substitute goods, the cross-price elasticity of demand is positive. This means that if the price of one good rises, the demand for the substitute good increases.
