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. No, because planting softwood trees have a higher profit per acre.2. No, because there is not enough information given to make a conclusion.3. Yes, because the chance of getting a similar result is small.4. Yes, because planting hardwood trees have a higher profit per acre.

The results are statistically significant because planting hardwood trees have a higher profit per acre.

Step-by-step explanation:

From the question above,

It shows that hardwood trees had a 46% higher Profit per acre than softwood trees.

Meaning that for every $100 made on softwood trees, $146 profit would be made on hardwood trees i(including both primary and secondary expenses; making the hardwood trees more profitable.

The information given is enough to reach a conclusion that planting hardwood trees have a higher profit per acre than softwood trees.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

$12. that is my answer.
