Investing

As you've read in your text, the overall percentage of U.S. citizens participating in a stock market either through individual holdings or through financial intermediaries such as mutual funds has declined since the 2008 recession. Prior to 2008, a greater percentage of Americans held stock market investments than do in 2018. This is an interesting characteristic, given the following factors:

1. Investing in the market through savings plans, 401k or 403b accounts, individual IRAs, or similar retirement plans has never been easier given the amount of information available to any individual. Individuals can invest small amounts such as $20 and benefit from dollar-cost averaging through automatic deposits and electronic transactions such as payroll deductions.
2. While a vast majority of Americans will be dependent on Social Security as their primary source for retirement income, the message that relying solely on SS for retirement continues to be broadcast by media outlets such as the AARP.
3. Since 2008, the markets have rebounded significantly from their 2008 lows.
4. Basic principles of investing are easily located on the internet, from a variety of sources. For example, see the "Index Card" resource posted in Week 5, which is a short list of fundamental investing principles.

For this discussion post, you are to state a position and present an argument related to the above state of investing by U.S. citizens today. Why has the overall percentage of Americans invested in the market decreased in the last decade? And, subsequently, what can be done about this? In your argument, which is to be supported by both textbook and outside research, delve into one or more of the primary concepts presented in this week's readings. These include the various stock market indexes, international markets, the role of the mutual fund industry, active versus passive investing, in addition to multiple other concepts.  

.Find some recent projections for the future path of the U.S. government debt as a percentage of GDP. What assumptions are made about government spending, taxes, and economic growth? Do you think these assumptions are reasonable? If the United States experiences a productivity slowdown, how will reality differ from this projection?

Utilizing the market for reserves and assuming that initially the federal funds rate is 0.5 percentage point below the discount rate but 0.5 percentage point above the interest rate paid on reserves,

a. Show what would happen to the federal funds rate if the FED decreased the discount rate by 0.3 percent

b. Show what would happen to the federal funds rate if the FED increased the interest rate paid on reserves by 0.75 percent

[Javascript] Create a function that gets the total amount and percentage of covid case data for each Age Group

in the covid cases data set(which contains the property "Age Group" in each case array).

Age Groups: 'younger than 18', 'between 19 to 28 Years', 'between 29 to 38 Years','between 39 to 48 Years','between 49 to 58 Years','between 59 to 68 Years','between 69 to 78 Years','between 79 to 88 Years', and'older than 89'

the function getSummaryOfAges(data) should return an Object with the following structure:

{

'UnknownAge': {

totalAmount: 27,

percentageOfTotal: 0.001

},

'younger than 18': {

totalAmount: 39,

percentageOfTotal: 0.074

},

'between 19 to 28 Years': {

totalAmount: 68

percentageOfTotal: 0.124

},

'between 29 to 38 Years': {

totalAmount: 59,

percentageOfTotal: 0.100

},

...etc

}

For the covid case Objects that don't have an Age Group value(meaning it's null).

Then these case Objects should be treated as the "UnknownAge" Age Group category

For each age category, calculate the total number of covid cases(500 cases), the total for each age group,

and finally the percentage of the total.

Example of case object:

Case = {

"Age Group": "29 to 38 Years"

},

{

"Age Group": "19 to 28 Years"

},

...etc

Let x be a random variable that represents the percentage of successful free throws a professional basketball player makes in a season. Let y be a random variable that represents the percentage of successful field goals a professional basketball player makes in a season. A random sample of n = 6 professional basketball players gave the following information.

(c) Verify that S_e ≈ 3.0468, a ≈ 8.188, b ≈ 0.5168, and x ≈ 73.167.

(e) Find a 90% confidence interval for y when x = 83. (Round your answers to one decimal place.)

(f) Use a 5% level of significance to test the claim that β > 0. (Round your answers to two decimal places.)

The percentage composition by mass of a certian feul is given as C 90%, H 3.5%, O 3% and remainder is incombustible. The fuel is burnt in air and the resulting dry analysis gave the following result by volume: CO2 12.7@, O2 7%, N2 remainder.

a) find the mass of air supplied per kilogram of fuel.

b) Determine the percentage excess air.

Measurements on the percentage of enrichment of 12 fuel rods used in a nuclear reactor were reported in the data below. Assume the population of interest is normally distributed

A. Test the hypotheses H0 : µ = 2.95 vs. H1 : µ > 2.95 at the 0.01 significance level. provide a copy of your R input and output, state your conclusion in context

B. Find and interpret the lower 99% confidence bound on the true mean percentage of enrichment. use the interval from your R output
