The population from 1975 to 2015 are given below

Year	1980	1995	2010	2020
Population In 1000s	10	20	32	44

Use the data given in the table to draw the population – time relation in X-Y graph
Use the Graphical extension Method to find the population in 2050
According to the plotted graph, use only one method (Geometric Increase method or Arithmetic Increase method) to find the population in 2050 (Explain why you select this method)
Use the estimated population in 2050 to design the main sewer pipe running 0.6 times full at maximum discharge. The water supplied from the water works to the town is at a rate of 200 LPCD. The manning’s n = 0.015 for the pipe material and permissible slope is 1 ‰. Variation of n with depth may be neglected. Check for minimum and maximum velocity assuming that the groundwater level is lower than the sewer pipe level.

Please put step by step in Minitab For the 15-year period between 1995 and 2010, ABC’s monthly return had a standard deviation of 5%. Matthew, a certified financial analyst, wishes to establish whether the standard deviation witnessed during that period still adequately describes the long-term standard deviation of the company’s return. He collects data on the monthly returns recorded between 1st Jan. 2015 and 31st Dec. 2016 and computes a monthly standard deviation of 4%. Carry out a 5% test...

From 1995-2010, the real exchange rate between the Australian dollar and the U.S. dollar (measured as the price of U.S. goods divided by the price of Australian goods) fell at an average rate of 5% per year. Over the same period, the average annual rate of inflation in Australia exceeded U.S. inflation by 2% per year. Given this information, what was the average annual percentage change in the nominal exchange rate between the two currencies,...
