Question
Bill Alther is a zoologist who studies Anna's hummingbird (Calypte anna referenced from: Hummingbirds, K. Long and W. Alther.) Suppose that in a remote part of the Grand Canyon, a random sample of six of these birds was caught, weighed, and released. The weights (in grams) were as follows:
right-tailed
left-tailed
two-tailed
The standard normal, since we assume that x has a normal distribution with known .
The Student's t, since n is large with unknown .

Will you reject or fail to reject the null hypothesis? Are the data statistically significant at level ?
At the = 0.10 level, we fail to reject the null hypothesis and conclude the data are not statistically significant. At the = 0.10 level, we reject the null hypothesis and conclude the data are not statistically significant. At the = 0.10 level, we reject the null hypothesis and conclude the data are statistically significant. At the = 0.10 level, we fail to reject the null hypothesis and conclude the data are statistically significant.
Fail to reject the null hypothesis, there is sufficient evidence that humming birds in the Grand Canyon weigh less. Reject the null hypothesis, there is sufficient evidence that humming birds in the Grand Canyon weigh less. Fail to reject the null hypothesis, there is insufficient evidence that humming birds in the Grand Canyon weigh less. Reject the null hypothesis, there is insufficient evidence that humming birds in the Grand Canyon weigh less.
