- Go to the St. Louis Federal Reserve FRED databaseand find data on the M1 money supply (M1SL) andthe 10-year treasury bond rate (GS10). Add the twoseries into a single graph by using the “Add DataSeries” feature. Transform the M1 money supplyvariable into the M1 growth rate by adjusting theunits for the M1 money supply to “Percent Changefrom Year Ago.”a. In general, how have the growth rate of theM1 money supply and the 10-year treasurybond rate behaved during recessions andduring expansionary periods since the year2000?b. In general, is there an obvious, stable relationship between money growth and the10-year interest rate since the year 2000?c. Compare the money growth rate and the10-year interest rate for the most recentmonth available to the rates for January2000. How do the rates compare?prepare a line graph and examine the relationship observe between the two countries Years Growth rate Unemployment rate % Trinidad and Tobago Japan Trinidad and Tobago Japan 2016 -5.6 0.8 3.2 3.1 2017 -3.0 1.7 3.3 2.8 2018 0.1 0.6 3.0 2.2 2019 -1.2 0.3 3.76 2.4 2020 -7.8 -5.8 6.74 2.94Briefly explain homoscedasticity and heteroscedasticity or draw a graph illustrating these.
- The following graph shows a rough approximation of historical and projected median home price is for a country for the period 2000-2024 (a) The median home price peaked at the start of the year ____ at $______ thousand. (b) The median home price was decreasing most rapidly at the start of the year ______ when it was $______thousand, and increasing most rapidly at the start of the year ______ when it was $_____thousand. Assuming that the trend shown in the graph continued indefinitely, the median home price would approach the value of $______thousand in the long term.A developing country's economy is based on exporting raw materials to the United States . The country sells raw materials for U.S. dollars and converts them to its own currency at current exchange rates. The table shows these exchange rates for the years 1990 to 2020 . Based on the graph, which conclusion best describes the country's economic situation between 1990 and 2000?About the size of New Jersey, Israel has seen its population soar to more than 6 million since it was established. The given graphs show that by 2050, Palestinians in the West Bank, Gaza Strip, and East Jerusalem will outnumber Israelis. Solve the projected growth of these two populations as given below, a. In 2000, the population of the Palestinians in the West Bank, Gaza Strip, and East Jerusalem was approximately 3.2 million and by 2050 it is projected to grow to 12 million. Use the exponential growth model A = A0ekt, in which t is the number of years after 2000, to find the exponentialgrowth function that models the data. b. In which year will the Palestinian population be 9 million?
- Storrs Cycles has just started selling the new Cyclonemountain bike, with monthly sales as shown in the table. First,co-owner Bob Day wants to forecast by exponential smoothingby initially setting February’s forecast equal to January’s saleswith a = .1. Co-owner Sherry Snyder wants to use a three-periodmoving average. a) Is there a strong linear trend in sales over time?b) Fill in the table with what Bob and Sherry each forecast forMay and the earlier months, as relevant.c) Assume that May’s actual sales figure turns out to be 405.Complete the table’s columns and then calculate the meanabsolute deviation for both Bob’s and Sherry’s methods.d) Based on these calculations, which method seems moreaccurate?Researchers have surveyed college freshmen every year since 1969. The Figure graph (attached herewith) shows that attitudes about some life goals have changed dramatically over the years. In particular, the freshman class of 2013 was more interested in making money than the freshmen of 1969 had been. In 1969, 42% of first-year college students considered “being well-off financially” essential or very important. For the period from 1969 through 2013, this percentage increased by approximately 0.9 each year. If this trend continues, by which year will all college freshmen consider “being well-off financially” essential or very important?B3 Calculate (predict) t = 11 for each trend method.
