A high school biology student wishes to test the hypothesis that hummingbird feeders can add additional weigth to the the mean mass of ruby-throated hummingbirds in the area surrounding the feeder. Studies indicate the mean mass of the hummingbirds to be 3.65 grams. She captures and weighs several of the hummingbirds near a science museum where several feeders are located. She obtains the following masses in grams:

4.2 3.9 3.6 3.6 3.9 3.8
3.8 4.1 3.9 3.8 3.2 3.4

1) State the null and alternate hypothesis.

2) Calculate P, then determine whether the data provide sufficient evidence to conclude that the mean mass of the birds in the area surrounding the feeder is greater than the mean mass of the general population. Test at the 0.05 significance level and assume that the population standard deviation is 0.35 g.

3) Interpret the results.
