The data from exercise 3 follow. excel file: data12-17.xls the estimated regression equation for these data is ŷ = 7.6 + .9x. compute sse, sst, and ssr (to 1 decimal). sse sst ssr what percentage of the total sum of squares can be accounted for by the estimated regression equation (to 1 decimal)? % what is the value of the sample correlation coefficient (to 3 decimals)? icon
SSE = 127.3
SST = 281.2
SSR = 153.9
percentage of the total sum of squares can be accounted for by the estimated regression equation is 54.7%
sample correlation coefficient = 0.736.
Step by step explanation: Please find the attached files for the solution
the answer is:
the correct option:
to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.
we are given the equation:
then, using placing logarith with base 7 on both sides of the equation, we have:
so, rounding the obtained result to two decimal places (nearest hundreth), we have:
hence, we have that the correct option:
have a nice day!
every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
