Answer:

P(X

And we can find this probability using the normal standard distribution table or excel and we got:

P(Z

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 expected return, and for this case we know the distribution for X is given by:

X \sim N(11,26)  

Where \mu=11 and \sigma=26

We are interested on this probability

P(X

And the best way to solve this problem is using the normal standard distribution and the z score given by:

z=\frac{x-\mu}{\sigma}

If we apply this formula to our probability we got this:

P(X

And we can find this probability using the normal standard distribution table or excel and we got:

P(Z

Flapjack Corporation had 7,953 actual direct labor hours at an actual rate of $12.00 per hour. Original production had been budg
uysha [10]

Answer:

The correct answer is:

$6,998.64 favorable (b)

Explanation:

The direct labor rate/price variance is the difference between the standard cost of production and the actual cost incurred in the production process. If the actual rate of labor is less than the standard labor rate, it is said to be favorable, because lesser time is used in the production process than estimated. The reverse is the case for unfavorable direct labor rate variance.

The formula is given as:

Direct Labor Rate Variance = (SR - AR) × AH

Where

SR = standard rate = $12.88 per hour

AR = actual rate = $12.00 per hour

AH = actual direct labor hours = 7,953 hours

∴ Direct labor rate variance = (12.88 - 12.00) × 7,953 = $6,998.64 favorable

natali 33 [55]

Answer:

Economic changes would not be considered a risk that needs to be analyzed as part of the risk assessment process.

Explanation:

Risk assessment is the process of identifying events that could potentially cause harm, to an individual, business or the environment and analysing them to get an acceptable tolerance level.

Risk assessment determines the likelihood of an event happening, it's impact, and tolerability the entity can take.

The environment is a major consideration of risk assessment, as risk is always inherent as business interacts with its environment.
