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:
B
Explanation:
Setting up realistic goals is key to saving money. Why would you want to save for a car when you are 12? You would rather save to get a new tablet or toy.
Realistic could also mean achievable why would you set a goal that has a low chance of you reaching such as becoming a millionaire and so on.
<u>Solution and Explanation:</u>
Required Return after 5 year = Real rate of return + Inflation premium + Risk premium
Required Return after 5 year = 5+2+4
Required Return after 5 year =11%
No of year left to maturity = 25
Annual Interest payment = 15%*1000 = 150
Face value of Bond = 1000
New price of the bond = pv (rate, nper, pmt, fv)
New price of the bond = pv (11%,25,150,1000)
New price of the bond = $ 1336.87
In building a new mall,
The input would be : Labor, All materials needed in building a mall
Conversion : Building process
Output : The actual mall itself

According to liquidity preference theory, a drop-off in money demand for some ground other than a change in the price degree causes The interest rate to go down, so the aggregate demand shifts.
<h3>What is aggregate demand?</h3>
The total amount of goods and services produced in an economy is the measurement of the aggregate demand.
The aggregate demand is shown as the total amount of money is exchanged at the particular price level and point in time.
Thus, The interest rate to go down,
