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:
$2000=Z/(1+i)^1+Z/(1+i)^2+Z/(1+i)^3
Explanation:
let Z be the annual minimum cash flow
The internal rate of approach can be used here, in other words, the rate of return at which capital outlay of $2000 is equal present values of future cash flows
In year 1, present value of cash =X/discount factor
year 1 PV=Z/(1+i)^1
year 2 PV=Z/(1+i)^2
year 3=Z/(1+i)^3
Hence,
$2000=Z/(1+i)^1+Z/(1+i)^2+Z/(1+i)^3
Solving for Z above would give the minimum annual cash flow that must be generated for the computer to worth the purchase
Assuming i, interest rate on financing is 12%=0.12
Z can be computed thus:
$2000=Z(1/(1+0.12)^1+(1/(1+0.12)^2+(1+0.12)^3)
$2000=Z*3.09497902
Z=$2000/3.09497902
Z=$646.21
