Question

Allen's hummingbird has been studied by zoologist Bill Alther. Suppose a small group of 15 Allen's hummingbirds has been under study in Arizona. The average weight for these birds is x=3.15 grams. Based in previous studies, we can assume that the weights of Allen's hummingbirds have a normal distribution, with o=0.22 gram.
find an 80% confidence interval for the average weights of Allen's hummingbirds in the study region. What is the margin of error? (Round your answers to two decimal places.)

lower limit=

upper limit=

margin of error=
