Local environmentalists want to test if there is a difference in the pH of three different streams (called A, B, and C) feeding into Lake Travis. They took a random sample of 15 measurements from each stream and, after confirming all relevant assumptions, ran a one-way ANOVA on the data and got a significant (p<0.05) result.

a. Write the appropriate null and alternative hypotheses for this analysis. (1pt)
b. List one potential confounding variable and briefly describe what impact it might have on the applicability of the results. (2pt)

This seems very difficult. Good luck!

Step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
