  1. Is there any evidence that there is a difference in small stem density, and basal area between the bird and random sites? Use a t-test to evaluate this. State your hypothesis clearly for each test, and describe your results. Interpret the meaning of your results.12 points.

Small stem density/ha t-test p-value: 0.46582

Small stem density/ha t-test t-value: 0.64208

Basal area t-test p-value: 0.02824

Basal area t-test t-value: 0.97751

I need help understanding how the t values from the t test determine if there is a significant difference in the two samples. 138 Degrees of freedom were used.

Is there strong evidence of global warming? Let's consider a small scale example, comparing how temperatures have changed in the US from 1968 to 2008. The daily high temperature reading on January 1 was collected in 1968 and 2008 for 51 randomly selected locations in the continental US. Then the difference between the two readings (temperature in 2008 - temperature in 1968) was calculated for each of the 51 different locations. The average of these 51 values was 1.1 degrees...

Two movie theaters are across the street from one another, in direct competition! Theater A takes a sample of 50 days, and finds that in that sample an average of 547 customers come through the theater each day, with a standard deviation of 42. They proudly display their results. Theater B takes a sample of 30 days and finds that in their sample, they have an average of 571 customers, with a standard deviation of 59. They claim this means...
