Conditions of the problem of control work
Option xx.
For these sample values \u200b\u200byi demand for certain goods and middle-income buyers xi
1) Find the point estimates of the parameters a and b of the linear regression of y on x and the sample regression equation y = ... + ... Chx;
2) Find the coefficient of determination R2 = ...;
3) find the confidence intervals for the parameters of the linear regression with a confidence level of g = 0,95 (... <a <...; ... <b <...);
4) to find confidence intervals for the conditional expectation M [y | x = x0] at two and x0 = x0 = xmax
... <M [y | x =] <...; ... \u003cM[y|x = xmax]\u003c… ;
5) find the confidence intervals for the individual values \u200b\u200bof y (x) for two values \u200b\u200bof x = and x = xmax
... <Y (x =) <...; ... <Y (x = xmax) <...;
6) Check the three hypotheses about the values \u200b\u200bof the coefficients b for two values \u200b\u200bof confidence level:
H0: b = 0,00 0,50 1,20
T =
g = 0,95 (Tcr =)
g = 0,99 (Tcr =)
7) to test the hypothesis on the significance of the linear regression equation
with a confidence level of g = 0,95 ... equation significantly since Fkr F = ... = ...;
with a confidence level of g = 0,99 ... equation significantly since Fkr F = ... = ...;
