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:
for breathing
Explanation:
since it holds the digestive and reproductive system
It considered that all terrestrial plant species that exist today have evolved from Rhyniophyta (a type of spore plants, compiled by the most primitive forms of vascular). Now terrestrial plants presents by the Moss family, psilotaceae, lycopsids, class of the Horsetail, fern, gymnosperms and flowering plants. Based on the cladogram, It assumed that the ancestors of all existing plants are algae, particularly green.
