n the Grand Canyon, a random sample of six Anna's hummingbirds were caught, weighed, and released. The sample mean was = 3.75 grams and σ = 0.70 grams. For the population of Anna's hummingbirds the mean is µ = 4.55 grams. Assume a normal distribution. Do the data indicate that the mean weight of these birds is more than 4.55 grams? Use α = 0.05. Complete a hypothesis test: a) What are Ho and H1? b) Are we using a z or t test? Why? c) Calculate z or t. d) What is p? e) Do we reject or not reject Ho and why? f) What is the conclusion? That is, do the data indicate the mean weight of the birds is more than 4.55 grams? Explain.
