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). Treatment 1 Treatment 2 Treatment 3 Block 1 969280 Black 2 979072 Block 3 948464\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} Block 1 Black 2 Block 3 Treatment 1 969794 Treatment 2 929084 Treatment 3 807264 Conduct a Friedman test at the 0.05 level of significance to determine if there are differences between the three diets.
Friedman Test
A non-parametric statistical test used to detect differences in treatments across multiple test attempts.
Level Of Significance
A threshold in statistical testing that determines if the evidence is strong enough to reject the null hypothesis.
Diets
