Examlex · Accepted Answer

The Answer is Let

\mu _ { d }

represent the mean difference

( \mathrm { A } - \mathrm { B } )

in time to wings level for treatments

\mathrm { A }

and

\mathrm { B }

\begin{array} { l } H _ { 0 } : \mu _ { d } = 0 \H _ { a } : \mu _ { d } eq 0\end{array}

The problem states that the assumptions for the

t

-procedure are met.

\begin{array} { l } t = \frac { \bar { d } - 0 } { \sqrt { \frac { s _ { d } ^ { 2 } } { n _ { d } } } } = \frac { - 0.2625 - 0 } { \sqrt { \frac { 2.9747 ^ { 2 } } { 8 } } } = - 0.2496 \P - ext { value } = 0.81 , d f = 7\end{array}

Since the

P

-value is very large, we cannot reject the null hypothesis. There is not sufficient evidence of a difference in mean recovery times to wings level between drinks

\mathrm { A }

and

\mathrm { B }

.
