Answer:
Explanation:
Data given and notation
represent the sample mean
represent the standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
t would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to determine if the mean is lower than 5600, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
We don't know the population deviation, so for this case is better apply a t test to compare the actual mean to the reference value, and the statistic is given by:
(1)
t-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
Calculate the statistic
We can replace in formula (1) the info given like this:

Answer:
(A) $40,000
Explanation:
At the time of recording of the fixed assets, the fixed assets should be recorded at purchase cost or historical price
Since in the question, the land was purchased at $40,000. Moreover, for the tax purpose, the land is valued at $27,000 and the qualified appraiser appraise the value at $48,000. The cash payment is also offered for $46,000
But at the time of recording or reported, the balance sheet would show at the purchase price i.e $40,000
The purchase and suppy of goods and services takes place in the product market.
Answer:
<em>The expected rates of return of stocks A and B:</em>
E(RA) = 0.1*((13%) + 0.2*(12%) + 0.3*(14%) + 0.2*(15%)
E(RA) = 13.2%
E(RB) = 0.1*(8%) + 0.2*(7%) + 0.2*(6%) + 0.3*(9%) + 0.2*(8%)
E(RB) = 7.7%
<em>The standard deviation of stocks A and B are:</em>
Var(RA) = [0.1*(10%-13.2%)2^ + 0.2*(13%-13.2%)^2 + 0.2*(12%-13.2%)^2 + 0.3*(14%-13.2%)^2 + 0.2*(15%-13.2%)^2]^1/2
Var(RA) = 1.5%
Var(RB) = [0.1*(8%-7.7%)^2 + 0.2*(7%-7.7%)^2 + 0.2*(6%-7.7%)^2 + 0.3(9%-7.7%)^2 + 0.2*(8%-7.7%)^2]^1/2
Var(RB) = 1.1%
