All of the options mentioned above are money market instruments.
A money market is an organized exchange market where participants can lend and borrow short-term, high-quality debt securities with an average maturity of one year or less. It includes instruments like tax anticipation notes, treasury notes, certificates of deposit, and commercial paper. It enables governments, banks, and other large institutions to sell short-term securities to fund their short-term cash flow needs. Money markets also allow individual investors to invest small amounts in a low-risk setting.
The money market contributes to the economic stability and development of a country by providing short-term liquidity to governments, commercial banks, and other large institutions. Investors with excess money that they do not need can invest in the money market and earn interest.

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)

Calculate the statistic
We can replace in formula (1) the info given like this:
