The Table Below Displays Data Showing Weight Gain,in Grams,for Nine

The table below displays data showing weight gain,in grams,for nine young rats,three from each of three litters.Three different diets (the treatments)were assigned at random to the three siblings in litter one (block 1).This was repeated for the other two litters (blocks 2 and 3). $$\begin{array} { | c | c | c | c | } & \text { Treatment 1 } & \text { Treatment 2 } & \text { Treatment 3 } \\\hline \text { Block 1 } & 96 & 92 & 80 \\\hline \text { Black 2 } & 97 & 90 & 72 \\\hline \text { Block 3 } & 94 & 84 & 64 \\\hline\end{array}$$ Conduct a Friedman test at the 0.05 level of significance to determine if there are differences between the three diets.
