Question

a foresting service conducted a survey to see if tree farms that planted hardwood trees were more profitable over a 30-year period than tree farms that planted softwood trees. the results of this study showed that hardwood trees had a 46% higher profit per acre. are the results statistically significant? (1 point)

yes, because planting hardwood trees have a higher profit per acre.

no, because planting softwood trees have a higher profit per acre.

yes, because the chance of getting a similar result is small.

no, because there is not enough information given to make a conclusion.

Explanation:

To determine statistical significance, we need to know if the result (46% higher profit) is likely due to chance or not. The options that just compare profit (first two) are wrong because statistical significance isn't about which is higher, but about the probability of the result. The third option's reasoning is about chance but we don't have info on that. The fourth option is correct because we don't have details like sample size, p - value, or how the survey was conducted to assess if the result is statistically significant.

Answer:

D. No, because there is not enough information given to make a conclusion.
