Neither prarie dogs nor cattle are a threat to burrowing owls. Prarie dogs and burrowing owls share predators, and prarie dogs are a vocal, alarm calling mammal species. Sometimes animals that share predators will eavsdrop on alarm calls that other animals emit. Hearing an alarm from another animal may result in alert behavior in the animal listening. You wish to know whether owls eavesdrop on prarie dog anti-predator alarms. You reason that if they do eavesdrop, the owls will become alert more quickly when they hear a prarie dog anti-predator alarm call than when they hear cattle moving. 1. Write a testable active hypothesis regarding differences in time to alert status in owls hearing a prarie dog alarm vs owls hearing cattle moving. 2. What is the null hypothesis? You broadcast each of these sounds Burrowing owls at your study site and measure the amount of time it takes for an owl to show alert behavior following the sound. You run a t-test on your collected data and get the output below: P value and statistical significance: The one-tailed P value equals 3×10^-3; The two-tailed P value equals 5×10^-3 Intermediate values used in calculations: t=2.87 df=96 Group Predator Cow Mean 1.61 seconds 2.80 seconds SD 0.56s 0.25s N 54 44 3. Write a results statements for these data. Make sure include ALL important elements. 4. Draw a correct graph to represent your results. SHOW WORK! • Show less
