Draw all formal conclusions given the data provided a t 12

Draw all formal conclusions given the data provided. a t (12) = .53, p >.05 b d = .62 c CI95 = [1.34, 3.22]

Solution

a) Given P>0.05, That means, We accept H0. Suppose P<0.05 we say that reject H0. In other way, calculated t value < = t - crtical value then we accept H0 otherwise we reject H0.

b) Generally, the difference between parameter value and the corresponding statistic value is d.

c) The parameter value will be lies between 1.34 and 3.22 at 95% confident.
