Answer:
0.0139
Explanation:
Given that:
The number of sample (n) = 21
The sample distribution has mean (μ) and a standard deviation of σ/√n
The z score is given as (x - mean)/ standard deviation
x = 94.8 wpm, let us assume that σ = 10 and μ = 90
Therefore: z = (x - μ) / (σ/√n) = (94.8 - 90) / (10/√21) = 2.2
To calculate the probability using Z table:
P(X>94.8) = P(Z>94.8) = 1 - P(Z<94.8) = 1 - 0.9861 = 0.0139
The probability is low that is less than 0.05, the program is more effective than the old one.
Answer:
Beta of a security is the covariance of the security return with the return on the market portfolio divided by variance of the market return.
The correct answer is C
Explanation:
Beta of a security is calculated as covariance (Ri,Rm) divided by Variance of the market return. Beta is used for measuring the systematic risk of a security.
Answer: Zero
Explanation:
The Correlation Coefficient measures the relationship between 2 variables under study and ranges from -1 to +1 which -1 meaning that the two are perfectly negatively correlated and +1 meaning they are perfectly positively correlation. A Correlation Coefficient of 0 means that there is no relationship.
An efficient market is one where all information is available to every market participant. This means that one cannot use information from one period to make abnormal profits in another period because all information is available. The Correlation Coefficient will therefore show 0 because information from the previous period is not being used in another period meaning there is no relationship between stock returns.
Answer:
Department M
Manufacturing overhead rate = $600,000/200,000 hrs = $3/hr
Department A
Manufacturing overhead rate = $400,000/800,000 hrs = $0.5/hr
Manufacturing overhead cost allocated:
Department M = $3 x 8,000 = $24,000
Department A = $0.5 x 12,000 = $6,000
Total manufacturing cost allocated = $30,000
Explanation:
This relates to overhead absorption. The manufacturing overhead rate is calculated as budgeted manufacturing overhead divided by budgeted direct labour hour.
Manufacturing overhead allocated = manufacturing overhead rate x actual labour hour for each department for the job.
Maybe a product didn’t work out, a bad review from a customer or client, health inspections didn’t pass etc..
