Null hypothesis (H0): The four treatment categories yield poplar trees with the same mean weight.
Alternative hypothesis (H1): The four treatment categories yield poplar trees with a different mean weight.
Based on the data table, it appears that Treatment A yields the highest mean weight for the poplar trees. Therefore, Treatment A appears to be the most effective.
To test the claim that the four treatment categories yield poplar trees with the same mean weight, we will use a significance level of 0.05. The null hypothesis (H0) assumes that the treatment categories yield poplar trees with the same mean weight, while the alternative hypothesis (H1) assumes that at least one treatment category yields poplar trees with a different mean weight.
To test the claim that the four treatment categories yield poplar trees with the same mean weight, we will use a significance level of 0.05. This means that if the p-value is less than 0.05, we will reject the null hypothesis and conclude that there is evidence to support the claim that the treatment categories yield poplar trees with different mean weights. On the other hand, if the p-value is greater than or equal to 0.05, we will fail to reject the null hypothesis and conclude that there is not enough evidence to support the claim that the treatment categories yield poplar trees with different mean weights.
The null hypothesis (H0) assumes that the treatment categories yield poplar trees with the same mean weight. The alternative hypothesis (H1) assumes that at least one treatment category yields poplar trees with a different mean weight.

Answer:
By the observation, the rod shape violet-colored bacteria could be a Gram-positive bacillus which is Lactobacillus spp. in curd.
Explanation:
Gram-stain is a staining method to isolate and study the Gram-positive or Gram-negative bacteria with the help of the crystal violet dye. Crystal violet dye stains both Gram-positive and Gram-negative bacteria in purple stain. After decolorization, Gram-negative bacteria appears to be pink in color, however,Gram-positive bacteria remain purple.
According to bacteria structure, they term as bacillus (rod), strepto (clusters or threads) or Diplo (in pairs).
Thus, according to the observation, the rod shape violet colored bacteria are Gram-positive bacillus which is Lactobacillus spp. in curd.
