In an analysis of variance problem involving 3 treatments and 10 observations per treatment, SSE= 399.6 The MSE for the analysis would be :
The average of 25 numbers is 36. If the average of first 13 numbers is 32 and that of the last 13 numbers is 39, then the 13th number is
An observation is drawn from an experimental distribution with mean θ, if the observation is found to be 2, and we test H0 : θ>1 against H1 : θ>1 with level e-3 then
For a trivariate distribution, if the correlation coefficients are r12 = r13 = r23 = r, -1 < r < 1, then r12.3 is:
Let x1,x2,....xn be a random sample of size n from N (µ , σ2) population where µ and σ are both unknown. For testing H0:µ = µ0 against H2:µ = µ1(±µ0) if one uses the test statistic
then H0 is rejected at level ∝
