4.Consider the following five observations on Savings and Income for a given population. (25 points) Y i 0.0 0.9 0.4 12.4 6.4 7.0 7.0 0.3 a) Assuming that Y_i are observations (in thousands of dollars) on savings, and X_i observations on income (also in thousands of dollars), compute by hand and showing all the steps you need to calculate, the regression coefficients β0, and β1 in the regression b) Write an equation for the fitted regression line considering the regression...
Please show your work. God bless 1. (40 points) Consider the following five observations. (9 points) (x-x) (x - x) (y- y) (x - x)(y-y) 2*- {x = 1012 (-:-)= {(x - 1)2 = 20;-)) = (x x)(y- » a) (6 points) What are the sample means of x and y? b) Complete the entries in the table above. Put the sums in the last row. (Show work below) c) Calculate Bo and write out the equation for the fitted...

stats help The percent of persons (ages five and older) in each state who speak a language at home other than English is approximately exponentially distributed with a mean of 5.1. a. The lambda of this distribution is b. The probability that the percent is larger than 3.94 is P(x23.94) - KOMME c. The probability that the percent is less than 8.3 is P(x 58.3) d. The probability that the percent is between 2.1 and 6.1 is P(2.1sx561)-
