Use Minitab to perform a Kruskal-Wallis test using the P-value approach.
-The table below shows the weights (in pounds)of 6 randomly selected women in each of three different age groups. At the 0.01 significance level, do the data provide sufficient evidence to conclude that a difference exists between the three population means? $$\begin{array} { l | l | l } 18 - 34 & 35 - 55 & 56 \text { and older } \ \hline 119 & 123 & 140 \ 134 & 147 & 128 \ 114 & 135 & 159 \ 125 & 110 & 134 \ 153 & 154 & 120 \ 138 & 163 & 116 \end{array}$$

The Answer is

\mathrm { H } _ { 0 } : \mu _ { 1 } = \mu _ { 2 } = \mu _ { 3 }

\mathrm { H } _ { \mathrm { a } }

: Not all the means are equal.

\begin{array} { l } \alpha = 0.01 \ p = 0.665 \end{array}

Fail to reject the null hypothesis. The data do not provide sufficient evidence to conclude that a difference exists between the three population means.
